This website is a record of my experiments in preparing interesting meals in a vacuum bottle, also known as a vacuum flask or "thermos," and actually using the insulating value of the vacuum between the walls to cook the food.
My husband and I camp, and we are crafters who sell our work at fairs. Getting a hot lunch at an outdoor selling event, especially if there are foods you can't eat, can be difficult. It's possible, of course, to just heat canned soup and bring it along, or make sandwiches, but after a little of that, and a LOT of dismayed reading of the allergen lists on various soup-can labels, I decided to see if I could actually make some of our favorite one-pot meals, from scratch, and have them cook in the soup-thermos in time for lunch.
So, for those who would like a hot lunch but can't or don't want to hit a restaurant every day, haven't time to cook lunch in the morning, and don't have leftovers to reheat, here are the results of my experiments!
Failed experiments are included along with the successful ones over on the "Experimental Process" blog, to help you in formulating your own recipes. Successful recipes will go under the tabs at the top (as you can tell, this hasn't been as easy as it sounds).
This website isn't about the technique of actually pulling a vacuum on your food in order to cook it. If that's what you came here looking for, there's a brief explanation at: http://www.epicurious.com/articlesguides/blogs/editor/2008/06/sous-vide-a-la.html, and more information to be found through a web search on sous vide.
