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 ↓
Doughnuts Without Eggs
Ingredients
Directions
Make the sponge
Scald the milk and let it cool until tepid.
Add the sugar, butter, yeast, and baking soda to the milk.
Pour this mixture into the center of the flour, using enough flour to make a sponge.
Let the sponge rise overnight in a warm place.
Shape and fry
In the morning, add your desired spices and knead in the remaining flour.
Let the dough rise again until light.
Knead the dough again and roll it out.
Cut out the doughnuts and let them stand for 5 minutes.
Fry the doughnuts in boiling lard.

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
- Provides the structure that holds the dough together and lets it trap gas.
- Milk
- Adds moisture and richness, and its proteins help give the dough a tender crumb.
- Yeast
- Produces gas as it ferments, making the sponge and dough rise and turn light.
- Sugar
- Feeds the yeast during fermentation and adds sweetness and some browning.
- Butter
- Adds fat, which softens the crumb and gives a richer flavor.
- Baking soda
- Reacts with acidity in the dough to release gas and add lift.
The step that matters
Frying in boiling lard. If the lard is not hot enough, the doughnuts absorb grease and turn heavy and oily; if it is too hot, the outside browns before the inside cooks through. Steady heat gives an even, light fry.
“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.
