Cookies are the easiest thing to bake and the hardest to bake the same way twice. Thirty-four pages on the five variables that decide what comes out of the oven - butter temperature, the sugar ratio, flour by weight, the leavener, and the heat - plus the full baker's percentage system, so you can fix a recipe with a number instead of a guess.

  • Why cookies spread, or don't: eleven causes and their fixes

  • 17-row troubleshooting table across two pages
