Cooking kits make from-scratch cooking convenient.

You can make kits for everything you want to cook. A kit for cookies might include all the dry ingredients that you're supposed to "sift together," so that, at another time, you can indulge an impulse to bake something sweet by jumping past the pesky prep. As one participant in The Nimble Cook Challenge observes, "the bar to completion comes down dramatically for me even by simply getting the dry ingredients measured and mixed."

What will you put in your cooking kit?
