woah. have you heard about cookthing yet?
pick a recipe for a simple dish. let's say, banana bread.
check off which ingredients you'd like to use in your banana bread. let's say, banana, baking soda, salt, vanilla extract, walnut, cinnamon, brown sugar, applesauce, and oats. click 'find recipes' and OMGZ!!!
assuming someone else likes to substitute as much as i do, i think i've pretty much found my resource for any basic recipe. i'll have to do a bit more poking around. very innnnteresting...
