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 ↓
Oatmeal Biscuits
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
Make the dough
Rub the butter into the flour.
Mix in the oatmeal, sugar, and baking powder.
Beat the egg and milk together, then combine with the dry ingredients to form a stiff paste.
Shape and bake
Roll out the dough very thin and cut into biscuits.
Bake in the preheated oven until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat that shortens the dough, giving a tender, crumbly texture.
- Flour
- Provides the structure that holds the biscuits together.
- Oatmeal
- Adds bulk and a nutty, toasted flavour and texture.
- Sugar
- Adds sweetness and helps the biscuits brown in the oven.
- Baking powder
- Releases gas that lifts the dough slightly as it bakes.
- Egg
- Binds the dough and adds richness and structure as it sets.
The step that matters
Roll out the dough very thin. Thin dough bakes through evenly and turns crisp. Thicker pieces stay soft in the centre and may not brown evenly before the edges darken.
