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 fairly hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Make the dough
In a bowl, mix the flour, oatmeal, baking powder, butter, and sugar.
Add enough cold milk to form a dough.
Shape and bake
Roll out the dough thinly and cut into shapes.
Bake for about 20 minutes until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the main structure that holds the biscuits together as they bake.
- Scotch oatmeal
- Adds a coarse, crumbly texture and a toasty oat flavour to the biscuits.
- Baking powder
- Releases gas during baking so the biscuits rise slightly and stay light.
- Butter
- Adds fat that tenderises the dough and contributes richness and flavour.
- Caster sugar
- Sweetens the biscuits and helps them brown to a golden colour in the oven.
The step that matters
Add enough cold milk to form a dough. Too much liquid makes the dough sticky and tough, while too little leaves it crumbly and hard to roll. Cold milk keeps the butter firm, which helps the biscuits stay tender.
