I have a handful of cookbooks stashed near the kitchen that I pull out again and again for the same old recipes (for variations, or because I forgot a temperature or a quantity).
I used to search through them every time I looked. Then I bought a small notecard box and copied down my favorites onto index cards, but that turned out to be rather annoying (writing out instructions by hand?). Maybe instead I'll buy some sticky tabs and label each page directly in the book.
So if you have a lot of cookbooks, and several recipes you go back to again and again, how do you keep them ready and convenient?
