As a truly amatuer cook I have found this most interesting. I know I am a much more inventive cook than my friends (mostly as a result of interest, travel, tasting) but never thought about the actual skills. Never could figure out why people can't follow recipes. Almost everything I've learned how to do I learned from books. Making a roux or dealing with shellfish, or even whole fish is not in my area of focus. The question of memory....and being able to do things without a recipe....is a problem. I rarely need a recipe for main dishes, (unless new and/or unfamiliar ethnic) and I could make good simple yeast breads without one. But even for Mother's famous blueberry muffins I check the quantities. Then I might tweak it. Is that lack of skill , practice, or lack of little gray cells? Also, much as I enjoy many kinds of foods I am at a complete loss to duplicate what I enjoyed beyond the most obvious ingredients. Memory is that I liked it, but memory of the actual taste disappears. Maybe more concentration is what's lacking. Is this a skill all high level cooks develop? Plus, do "real" cooks know how things will taste from the combination of ingredients?
