Why it works: Flour and nutmeg are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 18,623 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Hard Cookies

Oven, in the book's wordsA quick oven

Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Make the dough

  1. Cream the butter and sugar together.

  2. Add the eggs and mix well.

  3. Gradually add flour until a soft dough forms.

Shape and bake

  1. Roll out the dough and sprinkle with sugar and nutmeg.

  2. Fold the dough and roll it out again, sprinkling with sugar and nutmeg.

  3. Roll out very thin, sprinkle sugar and nutmeg on top.

  4. Bake in a preheated oven at 400°F (200°C) until golden.

  5. To keep cookies crisp, store them in a tin box.

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

What each ingredient does

Butter
Creaming with sugar traps air and gives the cookies a rich, tender structure.
Eggs
Bind the dough and add moisture and structure as they set in the oven.
Sugar
Sweetens the cookies and helps them brown and crisp as they bake.
Flour
Forms the dough's structure, which sets as the cookies bake.

The step that matters

Rolling the dough very thin. Thin dough bakes quickly and evenly, so it turns crisp rather than soft or doughy in the centre. Thick pieces stay soft and can scorch at the edges before the middle sets.

Swap the nutmeg

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

  1. Cinnamonfits about as well
  2. Nutmegthe original
  3. Jalapenofits less well
  4. Capersfits less well

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