Why it works: Flour and buttermilk are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 3,721 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

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.
Make the dough
Dissolve the baking soda in the buttermilk.
Rub the lard into the flour until well combined.
Mix all ingredients together until a dough forms.
Shape and bake
Roll out the dough to about 1 inch thick.
Cut into biscuit shapes.
Bake in a preheated oven at 400°F (200°C) until golden.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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.
- Buttermilk
- Adds moisture and tang, and its acidity reacts with the baking soda.
- Baking soda
- Reacts with the buttermilk's acid to release gas, helping the biscuits rise.
- Lard
- Adds fat that coats flour particles, producing a tender, flaky texture.
The step that matters
Mix all ingredients together until a dough forms. Mixing only until the dough comes together keeps gluten development limited, so the biscuits stay tender rather than tough. Overworking the dough makes the baked biscuits dense and chewy.
