Why it works: Butter and milk 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 ↓
Crullers
Ingredients
Directions
Make the dough
Mix the sugar and butter until well combined.
Add the eggs, sweet milk, and baking soda, mixing thoroughly.
Gradually add enough flour to form a stiff dough.
Roll out the dough and cut it into desired shapes.
Fry and serve
Heat lard in a lined saucepan until hot.
Drop the crullers into the hot lard and fry until puffed and browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Adds sweetness and helps give the dough a tender, browned crust.
- Butter
- Adds fat and richness, tenderizing the dough.
- Eggs
- Provide structure and binding, helping the dough hold its shape.
- Baking soda
- Reacts with the dough to help it rise and puff during frying.
- Flour
- Provides structure, forming the stiff dough that holds the cruller shapes.
The step that matters
Fry until puffed and browned. The lard must be hot enough before the dough goes in; if it is too cool, the crullers absorb grease and turn heavy instead of puffing and browning quickly.
“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.
