Why it works: Milk and butter 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 Tartar Biscuit
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.
Prepare the dough
Mix cream of tartar with flour in a large bowl.
Dissolve baking soda and coarse sea salt in a portion of the milk.
Add the milk mixture and melted butter to the flour mixture.
Knead the dough, dusting with flour as needed.
Bake
Cut out biscuits and bake in a 400°F (200°C) oven until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the biscuits together as they bake.
- Cream of tartar
- Acidic ingredient that reacts with baking soda to produce rising gas.
- Baking soda
- Reacts with the acid in cream of tartar to lift the biscuits.
- Milk
- Hydrates the flour and adds moisture and tenderness to the dough.
- Butter
- Adds fat for richness and a tender crumb.
The step that matters
Dissolving the baking soda and salt fully in the milk. Undissolved baking soda leaves pockets of bitter, soapy flavor and uneven rising, because it only reacts properly once it is evenly dispersed and meets the acid. Stirring until fully dissolved before combining helps the leavening spread evenly through the dough.
