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 with Baking Powder
Ingredients
Directions
Prepare the dough
Sift the baking powder into the flour.
Cream the butter and sugar with the egg yolks and whole eggs.
Add lemon extract and mace, then mix all ingredients together to form a smooth dough.
Shape and fry
Cut the dough with a doughnut or cruller cutter and twist them.
Fry the crullers until golden brown, similar to doughnuts.

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 main structure of the dough that holds the crullers together.
- Butter
- Adds fat for tenderness and richness in the dough.
- Egg yolks
- Add richness and help bind the dough into a smooth, cohesive mass.
- Baking powder
- Releases gas during frying so the crullers rise and become light.
- Sugar
- Adds sweetness and helps the crullers brown during frying.
The step that matters
Fry until golden brown. Frying at the right temperature cooks the interior through while the outside browns. Oil that is too cool makes greasy crullers, and oil that is too hot browns the outside before the center sets.
Swap the mace
How well each one fits the dish's main ingredients (flour, butter, sugar, egg, milk, lemon):
- Cinnamonfits better
- Nutmegfits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against flour, butter, sugar, egg, milk, lemon. Candidates are from the same food group and used in at least 100 recipes.
