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 ↓
Soda Biscuits
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Sift together the cream of tartar, salt, baking soda, and flour.
Rub in the butter until the mixture resembles coarse crumbs.
Quickly add the milk or water, kneading lightly to form a dough.
Roll out the dough to ½ inch thick and cut into desired shapes.
Bake
Place the biscuits in buttered pans and bake in a hot oven at 400°F (200°C) for 20 minutes.

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 once mixed with liquid and kneaded into dough.
- Butter
- Rubbed into the flour to add tenderness and flakiness to the baked biscuits.
- Baking soda
- Reacts with the acid in cream of tartar to release gas that helps the biscuits rise.
- Cream of tartar
- Supplies acid that reacts with baking soda, producing carbon dioxide for lift.
- Milk or water
- Hydrates the flour to form the dough and sets the structure during baking.
The step that matters
Quickly add the milk or water, kneading lightly to form a dough.. Handling the dough briefly and gently keeps it tender, because kneading develops gluten and overworking makes biscuits tough. The leavening reaction also starts as soon as the liquid is added, so the dough should go into the oven without delay.
