Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 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
- Eggs
- Beaten with sugar to trap air bubbles, giving the biscuit lift and a soft structure.
- Butter
- Adds fat for tenderness and richness in the dough.
- All-purpose flour
- Provides the starch and gluten structure that holds the biscuit together.
- Sugar
- Adds sweetness and helps browning as the biscuits bake to golden.
- Tartaric acid or baking soda
- Acts as a leavening agent so the biscuits rise and stay light.
The step that matters
Beating the eggs and sugar. Beating until pasty and full of air bubbles creates the foam that lightens the batter. Under-beating leaves a dense biscuit, so the foam must be well developed before folding it into the flour and butter.
