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 ↓
Plain Raised Doughnuts
Ingredients
Directions
Make the dough
Dissolve the yeast in lukewarm milk.
Stir in enough flour to make a thin batter and set aside to rise until foamy.
Add the beaten egg, sugar, salt, melted butter, and melted lard.
Stir in enough flour to knead into a stiff dough.
Place the dough in a greased dish to rise until soft to the touch.
Shape and fry
Turn the dough onto a floured board, cut into lengths, and twist.
Let the doughnuts rise for 45 minutes (longer if the weather is cold).
Fry in lard, placing them bottom side up; they should float if done correctly.

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
- Flour
- Builds the gluten network that gives the dough its structure and chew.
- Yeast
- Produces gas as it ferments, making the dough rise and become light.
- Egg
- Adds structure and richness, helping the dough hold its shape and texture.
- Butter
- Adds fat for richness and a tender crumb.
- Lard
- Adds fat for tenderness and carries the frying heat.
- Milk
- Hydrates the flour and yeast, forming the dough and adding softness.
The step that matters
Frying the doughnuts. Oil or lard must be hot enough to seal the surface quickly. If it is too cool, the doughnuts absorb grease and turn heavy; if too hot, the outside browns before the inside cooks.
“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.
