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 ↓
American Butter Cakes
Ingredients
Directions
Prepare the dough
Mix half cake flour and half bread flour, then sift with baking soda and salt three times.
Make a well in the center of the flour, add 6 cups of buttermilk, egg yolks, and melted butter.
Stir in the flour to form a slack, smooth biscuit dough.
Knead the dough well, then flatten it on a floured surface.
Let the dough rest until it loses its springiness, then roll to ¾ inch thick.
Shape and rise
Cut out biscuits with a 3-inch cutter and place in dusted boxes.
Cover and let rise in a cool place until about 1 inch thick.
Bake
Carefully lift out and bake on a hot plate or griddle on both sides.

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
- Provides the starch and gluten network that gives the biscuits their structure.
- Buttermilk
- Its acidity reacts with baking soda to produce gas, helping the biscuits rise and tenderize.
- Baking soda
- Reacts with the acid in buttermilk to release carbon dioxide for lift.
- Egg yolks
- Add richness and emulsify the fat, giving a tender crumb and smooth dough.
- Melted butter
- Adds fat for tenderness and flavor, coating flour particles to soften the crumb.
The step that matters
Let the dough rest until it loses its springiness. Resting relaxes the gluten developed by kneading. Rolling before it relaxes makes the dough spring back and produces tough, uneven biscuits.
