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 ↓
Southern Buttermilk 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 and salt into a large bowl.
Chop in the lard and butter until the mixture resembles the size of an egg.
In a separate bowl, mix the buttermilk with the baking soda and baking powder.
Knead the buttermilk mixture into the flour mixture until well combined.
Shape and bake
Mold the dough into small biscuits.
Bake in a preheated oven at 400°F (200°C) until golden brown.

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.

Flour and butter 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
- All-purpose flour
- Forms the main structure that holds the biscuit together as it bakes.
- Lard
- Cut into the flour to create flaky layers and a tender texture.
- Butter
- Adds flavor and flaky layers when cut into the flour and melted in the oven.
- Buttermilk
- Adds moisture and acidity that reacts with the leavening to lift the dough.
- Baking soda
- Reacts with the acidic buttermilk to produce carbon dioxide, helping the biscuits rise.
- Baking powder
- Releases gas as it reacts with moisture and heat, adding further lift and softness.
The step that matters
Chop in the lard and butter. Fat should stay in cold, pea-sized pieces within the flour. As it melts in the oven it releases steam that separates the layers, producing flakiness rather than a dense crumb.
“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.
