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 ↓

Ingredients
Directions
Make the paste
Boil the water, sugar, and butter.
Stir in the flour all at once and cook to a smooth paste.
Add the eggs one at a time, mixing well after each addition.
Shape and bake
Use a piping bag to shape the mixture into crescents, oblongs, or fingers on a greased baking pan.
Brush with beaten egg and sprinkle with pulverized sugar.
Bake until golden and fill with fruit jelly or a mixture of candied fruit and wine jelly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Starch cooked into the paste gives the puffs their structure and shape.
- Eggs
- Set in the oven to provide lift, structure, and richness in the dough.
- Butter
- Adds fat that keeps the paste tender and rich.
The step that matters
Adding the eggs one at a time. Each egg must be fully absorbed into the paste before the next goes in. Adding them too quickly can leave the dough runny or separated, so it may not hold its shape or rise properly in the oven.
“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.
