Given the background description of some cooking related query, summarize the question into a title
question:
I am often making a basic leavened bread for some basic recipes, like naan, burek, focaccia, pizza, etc. However, I find that dry active yeast is prohibitively expensive, considering it is a self-replicating living organism. Is there a way to effectively create and store yeast for a reasonable period of time (~3 months) from a mother spore?
answer:
How can I cultivate and store yeast?

question:
I'm preparing the court-bouillon recipe from James Peterson's Sauces (p. 103 of 3rd edition). The procedure is, roughly:Sweat vegetables,Simmer vegetables for 10 minutes,Add white wine and vinegar, simmering for a further 15 to 20 minutes, and thenCool and strain.My question is about step 3. For what reasons would the wine and vinegar be withheld for the first 10 minutes of simmering? Is this an evaporation issue? Or is there some deeper interaction between wine/vinegar and vegetables to be accounted for?Thanks!
answer:

question:
I am going camping shortly. I have done some dutch oven cooking before, and there is one recipe that I want to make that uses one. However, I do not have a dutch oven...I am thinking of using two aluminum pans (the cheap foil ones) and aluminum on the top (several layers) to make a sort of dutch oven alternative.Has anyone tried that? Does it work?I am also thinking of putting some sand or water between the two pans to make it hold and transfer the heat a little more evenly. Anyone know if this will work?
answer:
Dutch Oven alternative for campfire?
