Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Hard Biscuits

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the dough

  1. Warm the butter in a small saucepan.

  2. Add enough skimmed milk to make a stiff paste with the flour.

  3. Beat the mixture until smooth using a rolling pin.

Shape and bake

  1. Roll the dough thin and cut it into round biscuits.

  2. Prick the biscuits all over with a fork.

  3. Bake in a 400°F (200°C) oven for about six minutes.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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

All-purpose flour
Forms the structure of the dough, setting the biscuits as they bake.
Butter
Adds fat, which tenderizes the biscuits and gives them a richer flavor.
Skimmed milk
Hydrates the flour so it binds into a stiff paste that can be rolled.

The step that matters

Beat the mixture until smooth using a rolling pin. Working the stiff paste into a smooth dough develops even binding between flour and liquid, so the biscuits hold their shape when rolled and baked.

“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
