Why it works: Flour and almond are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
French Coffee Cake
Ingredients
Directions
Prepare the yeast and batter
Soak the yeast in 2 tablespoons of lukewarm water with a pinch of salt and 1 tablespoon of sugar.
Set aside to rise.
Cream the butter and powdered sugar together, stirring constantly in one direction.
Add the egg yolks one at a time and the grated lemon peel.
Sift the flour into a bowl, make a hole in the center, and pour in the yeast and lukewarm milk.
Stir to make a light batter.
Combine the creamed mixture with the batter until it forms bubbles and leaves the bowl clean.
Fold in the sultanas, pounded almonds, and finely chopped citron.
Gently mix in the stiff-beaten egg whites.
Bake
Pour the batter into a well-greased cake form.
Set in a warm place to rise.
Bake slowly, covered at first.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Yeast
- Ferments and produces gas so the batter rises and becomes light.
- Butter
- Adds richness and tenderness through fat that softens the crumb.
- Egg yolks
- Add richness, color and structure that helps bind the batter.
- Flour
- Forms the structure that holds the cake's shape as it bakes.
- Egg whites
- Trapped air from beating lightens the batter and helps it rise.
- Almonds
- Add body, nutty flavor and a moist, dense texture.
The step that matters
Folding in the stiff-beaten egg whites. Egg whites hold air only while their foam is intact, so mixing them in gently keeps the batter light. Stirring vigorously deflates the foam and produces a denser cake.
