Why it works: Raisin and flour match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butter: Adds fat that makes the cookies tender and helps them spread while baking.
Light brown sugar: Adds moisture and chewiness, and helps the cookies brown.
Flour: Provides the structure that holds the cookies together as they bake.
Baking soda: Reacts with the vinegar to produce gas that lifts and lightens the dough.
Baking powder: Releases gas during baking to help the cookies rise.
Vinegar: Reacts with the baking soda to add lift, taking the place of eggs in this eggless recipe.

The step that matters

Spacing the dough balls on the sheet. Cookie dough spreads as it bakes and softens, so placing too many balls too close together can make them merge or bake unevenly. Leaving room between them lets each cookie set on its own.

Swap the pecans

The recipe marks pecans as optional. How well each one fits the dish's main ingredients (butter, sugar, vanilla, oats, raisin, flour, vinegar):
