Why it works: Oats and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 1,532 recipes. Both carry alpha-pinene, which smells pine, turpentine. The science ↓

Oatmeal Snaps

Oven, in the book's wordsA slow oven

Ingredients

Directions

The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Make the dough

  1. Heat the molasses and butter in a saucepan until boiling.

  2. Gradually stir in the rolled oats and flour.

  3. Add the sugar and vanilla, mixing well.

Bake and shape

  1. Drop spoonfuls onto a buttered baking sheet, spacing them three inches apart.

  2. Bake at 300°F (150°C) until slightly cool.

  3. Remove from the pan and shape into calla lily blossoms.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Molasses
Adds sweetness, moisture and dark color, and helps the cookies brown.
Butter
Adds fat for richness and helps the cookies spread and crisp.
Rolled oats
Provide chewy texture and a toasty, nutty flavor.
Flour
Gives the dough structure so the cookies hold their shape.
Sugar
Sweetens the cookies and helps them turn crisp as they bake.

The step that matters

Spacing and baking until slightly cool. The molasses and sugar caramelize and the dough spreads as it bakes, so spacing the spoonfuls three inches apart keeps cookies from merging. The cookies firm up as they cool, so removing them at the right point determines whether they can be shaped.

Swap the vanilla

How well each one fits the dish's main ingredients (molasses, flour, butter, sugar, oats):

  1. Raisinfits about as well
  2. Vanillathe original
  3. Figfits less well
  4. Blueberryfits less well

Fit is the average pairing score against molasses, flour, butter, sugar, oats. Candidates are from the same food group and used in at least 100 recipes.
