Go to the Article: Tips & Tricks: Fizzy Fruit!
Do you think you could be a little more specific about how to make the fizzy fruit? For instance, how do you "arrange" the towel and the fruit with the dry ice in the container? Is the fruit supposed to be wrapped in the towel, or does the towel lay above or below the fruit? Where does the dry ice go? Just somewhere inside the container or does it have to be wrapped around the fruit with the towel or what? I have absolutely no idea how to make the fizzy fruit from the instructions above.
how long will the fizz last after hoping the bubble wrap?
Any idea how long this will last? Will it just lose carbonation, or will the added acid take its toll on the fruit? Regardless, I'll be trying this. Thanks!
I've done this in small batches with CO2 cartridges in my isi Whipping Canister for a few years . I've found grinding popping sugar in a coffee grinder then rolling the fruit in it takes it to an atomic popping fruit level. I also like to wrap carbonated grapes in gold leaf for fancy champagne grapes.
I love the whole cooler method for parties. Def have to do this for myy bday next weekend.
Min order for dry ice is 7kgs here. I am getting several pop bottles and doing the last thing public places... dun dun dunnnnnn. Just kidding.
Just had one of these explode at a school yard near here. Luckily no one injured. In my view it was irresponsible to add this trailer.
I agree, and have the same question.
Regarding how long the fizzyness lasts: I saw on different websites that the fizz goes pretty quickly. Two suggested you eat everything within 15 minutes of opening, another said within an hour. One provided a link for dry ice safety which has some important info.
Google is your friend. The answers exist on other websites.
Hi Brad, Grant explains in the video that the towel, or rag, is meant to cover the dry ice to separate it from the fruit so that the fruit won't freeze. Start with the dry ice in the bottom of the container, cover it with a towel, then arrange fruit around and on top of it. Wrap in plastic and wait for 12 hours (the smaller and colder the fruit, the faster it carbonates). That's it!
You definitely want to serve or eat fruit as soon as possible after taking it out of the cooler. You can leave it wrapped, in the cooler, for up to 24 hours. If you want to serve throughout an event you can separate fruit and dry ice into smaller containers, then use as you go.
Daniel: We love doing small batches in the siphon too. Here's directions for anyone who is interested: http://www.chefsteps.com/activities/carbonated-fruit--2
I love you Guys!!
You definitely want to serve or eat within 20 to 30 minutes of opening the container. If you want to serve fruit over the course of a longer event, we suggest making smaller batches in several different containers and opening them one at a time. You can leave fruit wrapped in the container with the dry ice for up to 24 hour.
The video didn't say anything about putting the cooler in the fridge. Is that what you are supposed to do?
1) Where in Seattle do I buy dry ice? Last time I tried to get some I finally had to go up to Ballard, which was super-annoying. Every store around (QFC, Safeways, etc) South Seattle acted like I was some type of irresponsible pyromaniac for wanting dry ice. "Why do you need it?" "To keep my popsicles frozen." "Just buy blue ice packs." "Those won't keep popsicles frozen for a 6 hour car ride in 100F weather." "Then make something else." "But I already made the popsicles." "Then you're out of luck, nobody will sell you dry ice." "Huh?"
2) I echo the question of, "How long does the fizzy fruit last?" As in do we take it out and have to eat it within 30 minutes at a party? Or will it last 2-3 hours? Or should I take it out in small batches for a party? Or what.
3) How do I convince my wife to let me buy an iSi whipper, she has been telling me no for 4 years now. "It's too expensive and all it makes is whipped cream." Boooo.
The cooler does not need to go into the fridge. The dry ice inside the cooler will keep the fruit cold and, as the dry ice sublimates back into gaseous CO2, it will also carbonate the fruit. The plastic wrap ensures that the pressure of the CO2 increases enough to dissolve plenty of fizz-making CO2 into the fruit. By using plastic wrap, you also ensure that the pressure cannot become dangerously high.
where oh where does one buy dry ice?
Is there a Cash and Carry near you. They have it. Uwajimaya and fish vendors have it. I've purchased it at many of the stores you mentioned. Not sure how far south you are. There are directories online if you Google for it.
You may not want to drive around for 6 hours, in 100 degree weather, with a bunch of dry ice. You should keep all of your windows open and put the dry ice in the trunk to make sure you are not filling your car with CO2. Everyone passing out from lack of oxygen is a very real possibility in that scenario. High CO2 levels can sneak up on you before you even are aware something is wrong. If you told stores you were going to do this it may be the reason they wouldn't sell it to you.
The time the fizz lasts depends on the temperature of the fruit and the pressures you attained when making it. As things warm, CO2 can leave solution fairly rapidly. I wouldn't think it would last longer than 30 minutes once you opened the cooler. The colder you can keep the fruit, without freezing it, the longer the carbonation will last.
Just read further and Jess Voelker from ChefSteps answered this below a couple of times as well.
Has anyone done this with corny kegs and a CO2 tank? Wondering about the pressure that would replicate the cooler effect. The iSi and 2 charges gives about 6 bar, right?
The video made it look like the carbonation levels were pretty high with just the sealed cooler and I don't want to waaaaaay over do it with the cornies.
You could use a pressure cooker to do the same and have the carbonation done in 1-2 hours.
It's a matter of skillful negotiation to get the whipper you want. Find out some expensive, one-task "thing" your wife really wants. Make sure it's in the price range of your whipper. Then, nonchalantly suggest a "splurge" day where she gets her item, and you get yours. My husband frequently asks to spend more and more money on his computer hardware. He figures out what I'm currently obsessed with, and the conversation begins...he gets his stuff, and I get my kitchen stuff!
How long does the fruit stay carbonated after removing from the cooler?
Jeff: Thank you. Jess had not answered the questions at the time I wrote my question. Good to hear Cash & Carry has it, and I had not thought of trying Uwajimaya! Thank you for the tips.
Municipal Fish did not have it and gave me a lecture about why consumers never need dry ice and how they never use it anymore, which is too bad because I rather like them as a business. I'm in the Columbia City area, both QFC and Safeway after discussing it with them claimed that as a chain they no longer carry dry ice or sell it to consumers as company policy, "Too many kids making bombs." Still rather frustrating.
Yes, I would not want to fill the car with CO2, which is something we had considered. To deal with that issue, we put the cooler on top of everything at the rear of the car and cracked the rear window open below it. Worked just fine, nobody passed out. The silliness of it all was that the popsicles started to melt by the time I found dry ice, and had refrozen by the end of the trip. Made for some wild and crazy shapes and people really enjoyed them.
Don, You want to serve the fruit as soon as possible after taking it out of the cooler, and within about half an hour. You can leave it covered in the cooler for up to 24 hours. If you want to stagger it so that you have carbonated fruit throughout the length of a party or evening, you could use several smaller containers and just unwrap each as you run out.
Looked the oranges were whole in the video. Will the CO2 get through the rind in 12 hrs, or was I hallucinating?
Yes, it will. And it's awesome when you peel into a cold orange, and then bite a fizzy segment.
Most grocery stores have it, although you often need to ask at the fish or meat counter.
Jay, this hasn't been my experience in Seattle at all. Every QFC I've been into, I just walk to the fish counter and ask for 5 pounds of dry ice. They wrap it up, slap a sticker on it, and sell it to me. Hasn't been awkward at all.
As for how long it lasts, the colder you keep the fruit the longer it will last. There is no hard or fast rule because it depends on a bunch of factors (surface area to volume, how much CO2 was initially dissolved into the food, how much water the food contains, etc, etc). But colder will always keep it fizzy for longer.
Can't help you with your wife. Apologize later and cook her something awesome using your new whipping siphon is my suggestion.
Watch the video at the top of the page. Grant puts the dry ice in the corner of the cooler with the towel covering it so that the fruit doesn't touch the ice. Then the rest of the container gets fill with the fruit.
I have done this in a whipping siphon per a previous post. This looks like a great way to do a large batch. But when you do it in the siphon, you charge it once, then immediately void the pressure. Then maybe even do that once more. Obviously, the purpose of that process is to void the normal atmospheric gas from the chamber so that it is primarily CO2. Then you charge with additional CO2 canisters and leave to sit in the fridge.
With this method, it obviously works great from the video but could it be enhanced by adding a similar voiding step? It seems this could be easily accomplished by putting a bowl of water (maybe warm) in with a small piece of dry ice in it. The cooler should fill with a dense cloud of CO2 vapor. So either:
Or would this even help at all?
Anyone have suggestions for using corny kegs and a CO2 tank. I was wondering what pressures people have used to avoid over/under carbonating. Looks like the iSi canisters get to 6 bar with 2 charges but that is some insane pressure for the kegs.
Thoughts on using a Pressure Cooker? Seems like a great device with a solid seal.
If you can safely control the pressure and have an accurate gauge. Pressure cookers are designed to blow at around 15psi over atmospheric pressure. If you don't know where the pressure is and the seal blows, you could have carbonated fruit all over and have to change the seals (and change your underwear because, holy cow, a pressure cooker is loud when it blows).
If the vents freeze over and pressure somehow can't escape it could literally become a bomb. With metal shrapnel. The plastic PET bottles injure people when they blow.
Cooler seems infinitely safer.
So. Doing.This.
I want to do this for some pre-teens at school. What if I had the dry ice in the cooler for 18 hours? And why doesn't the cooler explode?
So going to try the popping sugar!
Thanks Chris! Interesting, the Rainier QFC was friendly, compared to Safeways, but had a long explanation about why they do not sell it. I have Cash & Carry nearby, but never thought of going to them for dry ice but will do so in the future. You must have that, "Yes, I'm a chef, and I'm awesome" look to you, whereas I probably had that suspicious, "I'm a lawyer and I'm going to blow myself up" look. Who knows.
Good call on the siphon.
I will be trying this out for a party next Saturday!
Thanks Felicia. That is a good potential strategy. Maybe the next round of expensive prenatal vitamins will be packaged with a siphon.
I could see this working in a dial-based pressure cooker where you set the max pressure you want it to reach. Making sure it is dry beforehand so it will not freeze shut would be the trick, as I don't see a lot of water escaping from this particular scenario. The biggest issue is that there would be no safe way to relieve the pressure, because once you get to near 15psi you would have to remove the gaslock and the pressure would come out rather suddenly.
That said, I'm tempted to try this in a small, rocker-style pressure cooker put in a cabinet.
Tried it last night and opened it 12 hours later (this morning), didn't work for me, any thoughts why?
I soooo love you messy guys. Informative and hysterical at the same time. You guys are the best!
I'm guessing you didn't get enough of a seal on the cooler and the CO2 escaped before it could saturate the fruit.
Plastic wrap can't hold enough pressure to explode but just enough to carbonate the fruit. The excess CO2 vents safely through the gaps in the lid and wrap.
Was thinking water may come from condensation. I use a freezer for temperature controlling beer fermentations and there is condensation everywhere, even at temps as high as 65 degrees (granted the coils run near freezing). Cold metal can get wet very quickly.
I was just thinking worst, worst case scenario but it's one that may require lots of band-aids.
I had mixed results in a regular container. Seal was great, though I waited a bit too long , about 17 hours before serving. I'm going to try a cooler next time, I'm guessing the insulation will provide for a more forgiving time frame.
how long exactly does the fruit stay "fizzy"?
Denedim.Çok lezzetli keşfedenin ellerine sağlık....
About 20-30 minutes after you open the cooler.
don't do this.
if you soaked the fruit in alcohol first, could you make single bite fizzy fruit cocktails?
Which fruits need to be cut prior to getting sealed up? I noticed the watermelon went in cut, but what about the oranges, kiwi, etc?
how long will it stay fizzy after you open it, if I want to use it for a party? thanks!!! You guys are the best, I won't say it enough...
Simon
Hey Ben, double check the math. See my post above. Unless you threw a stupid amount of dry ice in the canner, I do not see this as a problem. Even if the gauge stuck.
With mine, I released the gauge slowly and the pressurized CO2 came out quite easily. I let it off slowly so that I did not create too fast of a pressure change for the fruit.
After two hours our grapes were still carbonated. Watermelon lost its carbonation in about 30 minutes. Skin and water levels of fruit definitely seem to impact sensation level as well as rate of loss, which makes sense.
Thanks Chris. I ended up getting it from Cash & Carry. They sell 6 pound blocks, which is huge but worked!
Soo... I didn't pay attention when y'all said one pound and the dry ice store said that it takes about 12 to cool for 24 hours... So, I got ten pounds in the cooler right now. Should I unpack that bad boy and dispose of about nine pounds of the dry ice? Will it explode on me? I'm using a styrofoam cooler wrapped in cling wrap.
Jay, make the 72-hour braised spare ribs in the sous vide. Then, accompany that with some mashed potatoes (I used an emersion blender for good texture) and creamed spinach foam (or espuma?). Make creamed spinach, hit it with the emersion blender, strain it, pour it into the siphon, charge, rekindle marriage. It's that easy.
A shipping and packaging business (fairly near my house and a farmer's market!) has dry ice and Styrofoam coolers that they use for shipping, but will sell to customers. They have one pound pellets and 5 pound blocks of dry ice, and sell many sizes of the coolers.
Hi Simon,
Optimally, you'll want to serve it within 20 and 30 mins. Certainly within the hour. You can always prep smaller containers of dry ice and fruit and stagger opening them throughout the length of an event. Happy fizzing!
Dear CheSteps team
I like the idea of fizzy fruits.
But can i make my own dry ice, for example, from the fire extinguisher "carbon dioxide"? because i dont have stores sell it in my cuntry.
Is it the same thing, or there is a special type of it is used in the food ?
How can i storage of dry ice ? And how long fruit storage and expire after a period of preparation and method of preservation ?
Thanks alot
Ghaith Sulaiman
It was an ISI siphon explode? While making carbonated fruit?
How can the dry ice be stored? Or do we have to use it right after buying it?
Dying to find out what happened here
.... SAME .... !!!!! .... !!!!! REPORT BACK
Freezer will extend the life, but use it as soon as possible so you done lose to much.
After the fizzy food is made, how long will they stay "fizzy'? What's the best way to keep them "fizzy"? Thx!
About 20-30 minutes after you open the cooler! You can also make several smaller batches and open them as needed.
For the life of me I am not able to make this work. I am using a Styrofoam cooler, 500 g of dry ice, and fruits like grapes, oranges, watermelon, and honeydew. We follow the steps and wrap the cooler in multiple layers of plastic wrap and let it sit 24 hrs but we are only able to get a slight, very slight, carbonation. I have no idea why the fruit isn't getting more carbonated, any suggestions on what we might be doing wrong?
That kind of cooler isn't air tight 100%... CO2 leaks out through the pores
I did 20psi for 24 hrs off the cuff, worked fine.
So, I clearly did not follow up. Better stupidly late than never... I do recall what happened, though: lots of frozen fruit, some fruit with fizz. No explosions, but it definitely stretched the (ridiculous amount of) cling wrap I had around that thing like a balloon.
