Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Pastry Crullers
Ingredients
Directions
Make the batter
Mix the flour and water together.
Add the butter, beaten eggs, and a little salt to the mixture.
Fry the crullers
Heat the cruller iron thoroughly in boiling lard.
Drain all the lard from the iron.
Dip the iron into the batter, ensuring it doesn't touch the bottom or sides of the cup.
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.

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 batter.
- Eggs
- Add richness and help bind the batter together.
- Butter
- Adds fat for tenderness and flavor in the batter.
- Boiling lard
- Cooks the batter quickly, browning the outside as it fries.
The step that matters
Dip the iron back into the boiling lard and fry until golden brown.. Batter that goes into lard that is not hot enough absorbs excess fat and turns greasy. Frying in properly hot fat sets the outside quickly and gives a crisp, golden crust.
