Why it works: Wheat and milk are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 2,418 recipes. Both carry (e,z)-2,6-nonadienal, which smells cucumber, melon. The science ↓
Cream of Tartar Biscuit
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 the flour, cream of tartar, and baking soda together.
Add the butter and work it into the flour.
Gradually add sweet milk to form a soft paste.
Roll out the paste on a floured surface to 1 inch thick.
Cut into small round or square cakes.
Bake
Bake in a hot oven at 400°F (200°C) for 10 to 15 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fine wheat flour
- Forms the main structure that holds the biscuit together as it bakes.
- Cream of tartar
- Acidic component that reacts with baking soda to produce gas for rising and a tender crumb.
- Baking soda
- Alkaline leavening that reacts with the acid to release carbon dioxide, lifting the dough.
- Sweet butter
- Adds fat that tenderizes the crumb and contributes richness and flavor.
- Sweet milk
- Hydrates the flour to form a cohesive dough and adds moisture for a soft texture.
The step that matters
Working the butter into the flour. Rubbing the butter into the flour coats the starch and limits gluten development, so the biscuit stays tender rather than tough. Overworking the dough after adding milk can toughen it and reduce rise.
“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.
