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 ↓
Good Cream of Tartar Biscuits
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Sift 2 cups of flour with the cream of tartar two or three times.
Sift the remaining flour into a mixing bowl and make a well in the center.
Make the dough
Add the flour with the cream of tartar, lard, salt, and baking soda dissolved in a little warm water, then mix well.
Gradually add the milk until fully incorporated.
Do not knead more than necessary.
Shape and bake
Roll out to about 1 inch thick.
Cut into shapes.
Bake in a moderate oven at 350°F (175°C) until light.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Provides the structure that holds the biscuits' shape as they bake.
- Lard or butter
- Coats flour particles to tenderize the crumb and help create flaky layers.
- Sweet milk
- Supplies the liquid that hydrates the flour and binds the dough together.
- Baking soda
- Reacts with the acid in cream of tartar to release gas that lifts the biscuits.
- Cream of tartar
- Acts as the acid that activates the baking soda for rising.
The step that matters
Do not knead more than necessary. Kneading develops gluten, the elastic protein network in flour. Overworked dough becomes tough and dense, so mix only until the milk is fully incorporated and handle the dough gently.
