I'm interested in both brewing and cooking. I would like to think that I succeed at a fair level at both. By no means am I a chef. There are a lot of things I could still learn about cooking, and tasting, but I always try to please family and friends and they seem to appreciate the effort.
If you want to learn how to cook better, I highly recommend watching Alton Brown for some basic science behind cooking, and also to find simple recipes online and then RESEARCH that food to compare with the recipe for accuracy in "style" (Some things you find online are very cheap or simplified imitations of the real thing).
Pick a favorite food and try to make it. If you don't get it right, find a different recipe or try again until you get it. Try to understand WHY you do what the instructions say. In time anyone can do basic cooking.
