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 ↓
Cream of Tartar Biscuits
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
In a large bowl, combine flour and cream of tartar.
Work in the softened butter until well incorporated.
Add the dissolved baking soda and sweet milk, mixing until a soft dough forms.
Knead the dough gently, then roll it out to a thickness of ½ inch.
Shape and bake
Cut into biscuit shapes and place on a baking sheet.
Bake in a preheated oven at 400°F (200°C) 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 of the dough once it is mixed and kneaded.
- Cream of tartar
- Acidic ingredient that reacts with the baking soda to produce gas, helping the biscuits rise.
- Butter
- Fat that is worked into the flour, adding tenderness and richness to the biscuits.
- Baking soda
- Alkaline ingredient that reacts with the cream of tartar to leaven the dough.
The step that matters
Add the dissolved baking soda and sweet milk. Baking soda and cream of tartar react as soon as they meet liquid, releasing carbon dioxide. Mixing the dough promptly and then getting it into the oven keeps that gas trapped, so the biscuits rise well.
