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 ↓
Buttermilk Biscuit
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
Preheat the oven to 400°F (200°C).
In a bowl, mix the buttermilk, baking soda, and melted butter.
In another bowl, rub the butter into the flour.
Beat the eggs until light and mix with the milk.
Stir the milk and egg mixture into the flour mixture.
Shape and bake
Add salt to taste and knead the dough.
Roll the dough thin and cut into biscuits.
Bake for 15 minutes until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Buttermilk
- Adds acidity that reacts with baking soda to lift the biscuits and gives a tender crumb.
- Baking soda
- Reacts with the acidic buttermilk to release carbon dioxide, helping the biscuits rise.
- Butter
- Rubbed into the flour as fat, it creates layers and a flaky, tender texture.
- All-purpose flour
- Provides the structure that holds the biscuits together as they bake.
- Eggs
- Add richness and structure, and help bind the dough.
The step that matters
Rubbing the butter into the flour. Butter should stay in small cold pieces coated in flour so it melts during baking and creates steam and layers. If it is overworked into a uniform mix, the biscuits turn out dense rather than flaky.
