Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
German Doughnuts
Ingredients
Directions
Make the dough
In a bowl, mix the bread sponge, eggs, sugar, butter, and a pinch of salt.
Let the mixture rise until light, similar to bread.
Shape and fry
Roll the dough to about ½ inch thick and cut with a small baking powder can.
Let the cut dough rise again.
Fry the dough in hot lard until they are almost round and golden.
Frost and serve
For the frosting, boil 1 cup of confectioner's sugar with 1 egg until smooth.
Serve the doughnuts warm with coffee.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bread sponge
- Provides the yeast-leavened base that gives the dough its rise and bread-like texture.
- Eggs
- Add structure and richness, helping the dough hold its shape and turn golden.
- Sugar
- Adds sweetness and helps the doughnuts brown when fried.
- Butter
- Adds fat for tenderness and richness in the dough.
The step that matters
Fry the dough in hot lard until golden. If the lard is not hot enough, the doughnuts absorb excess fat and turn greasy; if it is too hot, the outside browns before the centre cooks. Steady, moderate heat gives a light, evenly cooked doughnut.
