Why it works: Butter and flour 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 ↓
French Crullers
Ingredients
Directions
Make the dough
Mix butter, sugar, and water in a large bowl until well combined.
Gradually add flour and mix until smooth.
Incorporate eggs one at a time, mixing well after each addition.
Fry and serve
Prepare greased paper cut to the size of your cruller pot.
Spoon the mixture onto the paper.
Turn the paper upside down into boiling grease.
Remove the paper after half a minute, leaving the crullers in the grease.
Fry until they turn a nice yellow color.
Serve with vanilla icing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the dough together as it fries.
- Eggs
- Add richness and help bind and set the dough during frying.
- Butter
- Adds fat for tenderness and a richer flavor in the dough.
- Sugar
- Adds sweetness and helps the crullers brown evenly.
The step that matters
Remove the paper after half a minute, leaving the crullers in the grease.. Once the dough is set in hot fat, it releases from the paper; removing the paper too early can tear the shape, while leaving it too long keeps it greasy and blocks even frying.
“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.
