Why it works: Flour and milk are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. 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 flour, salt, baking soda, and cream of tartar in a bowl.
Add milk and stir thoroughly until the mixture fizzes.
Dredge a clean surface with flour and turn the dough onto it.
Quickly shape the dough into a ball without kneading.
Roll the dough into a sheet about 1 inch thick.
Cut and bake
Cut into rounds using a small biscuit cutter.
Bake in a preheated oven at 400°F (200°C) until golden.

Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure that holds the biscuit's shape as it bakes.
- Cream of tartar
- Acidic component that reacts with baking soda to produce gas for rising.
- Baking soda
- Alkaline component that reacts with the acid to leaven the dough.
- Milk
- Provides moisture to hydrate the flour and dissolve the leavening reaction.
The step that matters
Quickly shape the dough without kneading. Once liquid meets the acid and alkali, gas forms right away and starts to escape. Kneading or delay wastes that lift and toughens the gluten, leaving a dense biscuit.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
