Why it works: Flour and cinnamon are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 17,341 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Pastry Crullers
Ingredients
Directions
Make the batter
In a bowl, mix the flour and water until combined.
Add the butter, beaten eggs, and a little salt; mix well.
Fry the crullers
Heat the cruller iron in boiling lard until thoroughly hot.
Drain excess lard from the iron, then dip it into the batter in a pint cup, avoiding contact with the cup's bottom or sides.
Dip the iron back into the boiling lard and fry until golden brown.
Remove the cruller from the iron and reheat the iron before repeating.
Serve plain or sprinkle with cinnamon sugar.

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 batter once combined with liquid.
- Eggs
- Add structure and richness, helping the dough hold its shape while frying.
- Butter
- Adds fat for tenderness and a richer flavor in the batter.
- Boiling lard
- Fries the batter quickly, turning its surface golden brown and crisp.
The step that matters
Dip the iron into the batter without touching the cup. Batter that touches the cup's bottom or sides can stick and misshape the cruller. Keeping the iron clear lets the batter release cleanly into the hot lard.
Swap the cinnamon
The recipe marks cinnamon as optional. How well each one fits the dish's main ingredients (flour, egg, butter, sugar):
- Cinnamonthe original
- Nutmegfits about as well
- Jalapenofits less well
- Capersfits less well
Fit is the average pairing score against flour, egg, butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
“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.
