I was thinking about this the other day, I suppose one of the reasons might be that most of the DIY stuff to make an immersion circulator would appeal more to men tinkering than to women? I am sure both men and women have made DIY stuff but all the reviews and posts I have seen have been from men. (like on Amazon)
Other than that I have not a clue....
My wife doesn't really cook at all. I think she would have the same response as your wife did. I am not sure how we could make it more simple (It seems really simple to me) I was thinking since I could prevac it and freeze it, then just set the Polyscience Professional chef to the right temp, tell her to turn it on, put X piece of frozen food in and wait say an hour. Remove bag of stuff from water, cut open, dry said stuff, sear said stuff in a hot pan, enjoy said stuff.
So far shes not too keen on the idea since I always seem to be around to do it. To me it doesn't seem any more complex than baking a frozen pizza or microwaving a frozen meal.... there are still about 6 steps involved with all of them. And to be perfectly honest, the circulator has 4 buttons, the oven has about 14 and the microwave has 20..... so it still seems the most simple, plus you can really over cook it if it's in there for an hour.... I don't know what the deal is or why it seems intimidating, I guess it's the old story of leaving your comfort zone and stick with what you know...
@Susan_Fox Yes I agree that it is just preparing at that point, and yes i think over time it will become more mainstream, I don't know why any circulators or water baths have been used on network cooking shows. I know the number one thing on Alton Brown's list of things people had wished he had covered with Good Eats was Sous Vide. So I think people who are interested in cooking, like folks like ourselves are interested, they just need a more accessable way to access a unit, as with any new technology time will drive the price down, but I would bet money that if it was used on a network cooking show people who cook occasionally would be much more interested in a simple, easy, way of preparing food that they already cook.
If someone could make an immersion circulator in the $200 dollar price range, I think it would be a winner, not something that is used everyday, but maybe once or twice a week, and something that could fit in a pot people already own. Again vaccum sealing will push that to about $300 dollars right away putting it out of the reach of "part time" cooks.
I have a 60" flat screen mounted on the wall across from my kitchen, I have an Island with the cooktop and oven facing it so I get to enjoy both (The reason I wanted to buy this house was for the kitchen, well and the italian marble master bathroom!)
But I agree, i am not a huge TV person, I normally have music playing on it while I cook. I have a hard time sitting in one place for very long, I would rather be doing something.
@Lachlan My wife wasn't convinced either about the whole buy stuff in bulk or on sale and seal it and then eat it whenever you want, but after you have the freedom to come home and choose between a frozen pizza or a juicy perfectly cooked steak (by the way you can go take a shower or do stuff while the steak cooks, you have to watch the pizza so it doesn't burn) for about the same price, you will always find motivation to seal and freeze in advance, we have found that it really allows us to eat a lot healthier as well.
As for not having an immersion circulator yes the baby sitting a stovetop method seems like a pain but if you make the jump to a waterbath of some sort you will really get an understanding of how easy it is.
As for the not being able to cook 2 different temp foods at the same time (protein and veggies) I have run into the same problem. I cook the protein first, then put it in hot water in an ice chest. I remove about half of the water in the bath and then add boiling water to quickly raise the temp for veggies. Veggies go in, protein stays warm, dry and sear protein as veggies finish, plated together you get hot perfectly cooked protein and hot fresh veggies.
Since you don't have the immersion circulator I would in your case, cook veggies first, shock in ice water bath and place in fridge, then cook protein at desired temp and the last 5 to 10 minutes I would add the veggies to the pot of water the protein is cooking in to bring them to temp, but they won't overcook as the temperature is lower than what they were cooked at. Kill the heat in the pot, remove and dry then sear protein and then plate hot veggies and protein together.
