Why it works: Flour and almond are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Shortbread Biscuits

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Preheat the oven to 350°F (175°C).

  2. Mix the flour, chopped almonds, and sugar in a bowl.

  3. Knead the softened butter into the flour mixture until a smooth dough forms.

Shape and bake

  1. Roll out the dough thinly and cut it into finger lengths, about 1 inch wide.

  2. Place the biscuits on a clean, floured baking sheet.

  3. Bake until lightly browned.

  4. Let the biscuits cool on the baking sheet.

Assemble

  1. Spread jam on one biscuit, top with another, and sprinkle with sugar.

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

What each ingredient does

Butter
Provides fat and richness, giving the biscuits their tender, crumbly texture.
Flour
Forms the structure of the dough that holds the biscuits together.
Sugar
Adds sweetness and helps the biscuits brown lightly in the oven.
Round almonds
Add nutty flavour and a slightly crunchy texture to the dough.

The step that matters

Knead the butter until the dough is smooth. Butter must be softened so it blends evenly into the flour. Overworking the dough can make it tough, while under-mixing leaves greasy or crumbly patches.
