Chocolate chip cookies, compared

Chocolate chip cookies are the most-argued recipe in baking, and the arguments are all about ratios. Brown sugar against white decides chew against crisp; melted butter against creamed decides spread; and the recipes that tell you to chill the dough are making a different biscuit from the ones that don't. The bake window is narrow — a couple of minutes separates soft-centred from crunchy — which is why seeing every recipe's temperature and time together is more useful than reading any one of them.
