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 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, salt, and baking soda together.
Rub in the lard until well combined.
Add buttermilk gradually to form a stiff dough.
Shape and bake
Roll the dough to ½ inch thick and cut out biscuits.
Bake in a hot oven at 400°F (200°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Winter wheat flour
- Provides the structure that holds the biscuits together as they rise.
- Baking soda
- Reacts with the acid in buttermilk to produce gas that lifts the biscuits.
- Lard
- Coats flour particles and shortens gluten strands, giving a tender, flaky crumb.
- Buttermilk
- Adds moisture to form the dough and its acidity activates the baking soda.
The step that matters
Add buttermilk gradually to form a stiff dough. Adding liquid slowly lets you stop once the dough just holds together. Too much liquid or excess kneading develops gluten, which makes biscuits tough and dense.
