Oatmeal Raisin Cookies

The oatmeal cookie grew out of the Scottish and British tradition of oatcakes, carried to America, where rolled oats became a cheap, plentiful pantry grain. An early sweet oatmeal cookie recipe appears in Fannie Farmer's 1896 Boston Cooking-School Cook Book, where such cookies were promoted as a health food. The cookie became a household staple after the Quaker Oats company began printing a recipe on its canister in the early 1900s, putting the formula in front of millions of home cooks. Raisins were a natural and well-documented addition, encouraged in part by California raisin growers who printed oatmeal-raisin recipes in their own cookbooks in the 1910s. The cookie has no single inventor; it is a product of cereal- and fruit-company marketing layered on an old grain tradition.

The first thing you feel is chew — a substantial, slightly springy bite from the oats, with crisper, lacier edges and a soft middle. Cinnamon and brown sugar give a warm, caramel-toffee flavor, and the oats add a nutty, toasted, almost grainy note. The raisins are chewy and sweet, releasing pockets of concentrated fruit, and a touch of salt keeps the whole thing from going flat. It eats like a heartier, more textured cookie than its smooth-doughed cousins.

Rolled oats are the structural twist: they absorb moisture and add bulk and bran, giving the cookie its chew and rustic, broken texture rather than a smooth crumb. Brown sugar, rich in hygroscopic molasses, holds water and keeps the cookie chewy, while also driving the browning and caramel notes. Because the dough has plenty of fat and only moderate flour, it spreads into thin, chewy-edged rounds; chilling the dough or adding an extra oat or two reins in the spread for a thicker cookie. Toasting builds flavor in the oats through the Maillard reaction, and the raisins, plump and sweet, draw a little moisture from the dough as they soften, so soaking them first keeps the crumb from drying.
