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 ↓

Ingredients
Directions
Make the dough
Sift the flour, sugar, and baking powder together.
Rub in the lard and butter.
Add the beaten eggs, extract, and milk.
Mix into a smooth dough, just soft enough to handle.
Shape and fry
Roll out on a well-floured board and cut into strips about 1/4 inch square.
Twist into different shapes and fry in plenty of hot lard until light brown.
Serve with sifted sugar.

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
- Forms the structure of the dough once mixed with liquid and fat.
- Lard
- Rubbed into the flour to add tenderness and richness, and serves as the frying fat.
- Butter
- Adds flavor and richness to the dough, tenderizing it along with the lard.
- Eggs
- Bind the dough and add richness and structure to the fried crullers.
- Baking powder
- Releases gas that helps the crullers rise and become light in the frying fat.
The step that matters
Frying in hot lard. If the lard is not hot enough, the crullers absorb excess fat and turn greasy and heavy. Enough hot lard keeps the temperature steady so they brown lightly and cook through.
Swap the nutmeg
How well each one fits the dish's main ingredients (flour, butter, sugar, milk, egg):
- Cinnamonfits better
- Nutmegthe original
- Jalapenofits less well
- Capersfits less well
Fit is the average pairing score against flour, butter, sugar, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
