Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Doughnuts
Ingredients
Directions
Make the dough
Warm the milk and dissolve the yeast in it.
Stir in about 1 lb. of flour and the sugar, cover, and let it rise in a warm place until it drops.
Once it drops, add the melted butter, egg, and a pinch of salt; mix well.
Add enough flour to make a workable paste, then cover and let it prove in a warm place.
Shape and fill
When well proved, turn out onto a floured board, divide into 2 oz. pieces, and flatten slightly with a rolling pin.
Dampen the edges, place 1 spoonful of raspberry jam in the center, and fold the edges over to form balls.
Pinch them together firmly and place on a floured cloth, covering with another cloth to prove again.
Fry and serve
When light, heat lard in a pot and drop in the doughnuts, cooking for about 7 minutes on each side.
Remove with a drainer onto clean kitchen paper, then roll in caster sugar and serve.

Butter and flour 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 gluten network that gives the dough structure and lets it hold its risen shape.
- Yeast
- Produces gas as it ferments, making the dough rise and become light.
- Milk
- Adds moisture and richness, and its sugars feed the yeast and help browning.
- Butter
- Adds fat that tenderises the crumb and gives a softer, richer texture.
- Egg
- Adds structure and richness, helping the dough bind and hold its shape.
- Sugar
- Feeds the yeast during proving and adds sweetness and browning.
The step that matters
Proving the shaped doughnuts until light. Under-proved doughnuts stay dense and may burst or absorb more fat, while over-proved ones collapse in the hot lard. Gas from the yeast must fill the dough before frying.
Swap the raspberry

Fit is the average pairing score against milk, egg, sugar, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
