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 of the biscuit as its gluten and starch set in the oven.
Lard
Coats flour particles to tenderize the crumb and keep the biscuit short.
Milk
Hydrates the flour so the dough holds together and bakes moist.
Baking powder
Releases carbon dioxide gas that makes the biscuit rise and lighten.
Baking soda
Reacts with acidic components to produce gas for rising and light browning.

The step that matters

Add the milk and knead quickly. Overworking wheat dough develops gluten, which toughens the biscuit. A quick, light knead keeps the texture tender and flaky.
