For perfectly baked cookies, use a light-colored quality cookie sheet. You want the cookie bottoms to be ever-so-slightly browned, so undercook them just a little bit. Cookie dough can be made in advance and frozen, allowing you to bake cookies quickly whenever you choose!
I keep a bottle of dried parsley in the fridge and dust every dish with a little dried, or even better, fresh parsley. This helps the kids realize there is no such thing as “white food,” and it gets them used to the idea that herbs are supposed to be in food.
