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 ↓
Dough Nuts with Jam
Ingredients
Directions
Make the dough
In a bowl, mix flour and sugar.
Rub in the butter until well combined.
Add baking powder and enough egg to form a stiff dough.
Turn the dough onto a floured surface and roll it out thinly.
Cut the dough into small rounds.
Fill and fry
Place a little jam on half of the rounds and cover with the other rounds.
Dampen the edges and press them together firmly.
Heat oil in a pan and fry the doughnuts for about four minutes until golden.
Remove from oil, place on a dish, and sift sugar over them.

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 structure that holds the dough together and sets when fried.
- Butter
- Adds fat that tenderises the dough and gives a rich texture.
- Eggs
- Bind the dough and add moisture and structure.
- Baking powder
- Releases gas that makes the doughnuts rise and turn light.
- Sugar
- Adds sweetness and helps the doughnuts brown when fried.
The step that matters
Sealing the edges. If the edges are not dampened and pressed firmly, they can separate in hot oil, letting jam leak out and oil soak in. A tight seal keeps the filling inside while the dough cooks.
“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.
