Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ingredients
Directions
Make the batter
Heat 1 pint of sweet milk and melt 2 ounces of butter in it.
Add 1 pint of cold milk and the well-beaten yolks of 4 eggs.
Stir in 1 teaspoon of salt and 2 tablespoons of potato yeast.
Add enough flour to create a stiff batter.
Set the batter in a warm place to rise for 3 hours or overnight.
Cook
Before baking, fold in the beaten egg whites.
Fry the batter like any other griddle cakes.

Butter and flour 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
- Flour
- Forms the stiff batter structure that holds the cakes together when cooked.
- Potato yeast
- Ferments the batter during the long rise, producing gas that makes the cakes light.
- Egg yolks
- Add richness and emulsify the fat into the batter, giving a tender crumb.
- Egg whites
- Whipped and folded in, they trap air that adds lightness to the cakes.
- Butter
- Adds fat for richness and a tender texture in the finished cakes.
The step that matters
Set the batter in a warm place to rise. The yeast needs warmth and time to ferment; a cold or rushed rise leaves the cakes dense and flat. Folding in the egg whites only after the rise keeps their trapped air from collapsing.
