Liquid Nitrogen

Ok, filled the dewar....... did some raspberries, blackberries and orange slices......then some chocolate mousse, some peanut butter (oh my) and toasted pumpkin seed oil. The kids had a giggle fest when steam came out their nose while eating the chocolate mousse. It was even funnier to watch them try to recreate it..... LOL! ........I'm not sure, but I may need to join.......or create the
group..... Liquid Nitrogen anonymous..........I'm afraid I might just be
getting started.

So what does one do on a rainy saturday? get out the LN (Now I know what CS does in the winter ;-)...).
Had lots of fun with peanut buttter, almond butter, cocoa gelato, carrot juice (which are now frozen as speheres, just have t figure out what to do with them :-). The inside-out PB cups weer probably the "neatest" as everyone loved them. However, when I made the cocoa gelato, ok, I didn't get it before, but now I do.....wow!!. It is a bit technique sensitive and the torch on stand by is definitely a good idea for a begginer like myself, BUT, I received a "WOW that's the smoothest I've ever had" and then I tried it.........which is why I then shrugged. It was really that much smother than using an ice cream attachment. So an afternoon (so far) of "I get it now". Lots of work to still do, but I get.

Reverse PB Cup

I know it should have cut it with a knife, seriously? who am I kidding, it was rather tasty.

Cocoa Gelato with LN- Folks, try it if you can, I'm still in awe of the smoothness of such a desert. And yes, I know, chill the plate, before plating gelato etc.....had a bit too much on my mind. :-)

where do you find the " pot " to work with the liquid nitro ? seems like a friend of mine can fix me some liquid nitro to try it, but not sure which tools do i need, beside the spoon

I have a number of stainless steel bowls to pour into (which I house in a styro-foam cooler). A dewar is best for transport or at least vacuum insulated dispenser (ensure it does NOT seal! or it may explode). I tend to disagree with some of the experts on things like gloves (depending on use). For example, why wear gloves if the concern is splashing...if you get LN trapped inside the gloves that could get REALLY uncomfortable. I have kevlar and thermal (rubber-"like") gloves that I wore when pouring the LN for the sorbet, but if you have a small dewar, that's less of a worry. Look up Dave Arnold's Primer on Liquid nitrogen. Some REAL good tips. I'm sure (and hope) others will chime in. It was actually much easier than I thought to get and after a few days of using it, am much more comfortable with safety boundaries (they are there, I'm just much less paranoid).

What dewar are you using? They don't appear to be very cheap, though I am tempted.

Hi Seth, I am using a 20L dewar rented from Eric Glenn (Cryogenic Services, Inc.). Monthly rental is not expensive, but filling it for what you get is a bit expensive. I paid about $50. Which isn't terribly expensive, but for just over double that, I can get ~150L. The challenge is arranging to have a 150L Dewar. :-) I rented the small dewar to gauge how much I would use it and I have used it a fair bit (just early this morning I used it to make some passion fruit bon bons). The monthly rental prices aren't bad, but if you can arrange a larger one, you'll get allot more out of it. I'm asking some locals and there is an outside chance I can arrange for one. The liquid nitrogen itself was much easier to obtain than I would have thought. My recommendation would be to rent one (go for at least 25L) for a month or two to see if you would use it (and if so, how much). If you know you would instantly become a LN ninja, then contact your local welding suppliers and schools (some teachers are willing to at least try to help) and see about getting a much larger one (100L+).
