Why it works: Butter and milk 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 ↓

Ingredients
Directions
Make the dough
Sift the flour, salt, and baking powder into a bowl.
Rub in the butter and lard mixture, then stir in the milk until a medium dough forms.
Turn the dough onto a well-floured surface, knead lightly, and roll out to ¾ inch thick.
Fill and roll
Scatter the sliced peaches over the dough, sprinkle with sugar and nutmeg.
Roll up the dough like a jelly roll and secure it in a moistened and floured pudding cloth.
Cook
Boil for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the dough that holds the roll together while it cooks.
- Butter and lard mixture
- Adds fat that tenderizes the dough and keeps it moist.
- Baking powder
- Releases gas during cooking so the dough rises and turns light.
- Milk
- Hydrates the flour so the ingredients bind into a workable dough.
- Sliced peaches
- Provide moisture and fruity sweetness that soaks into the dough as it cooks.
- Granulated sugar
- Sweetens the filling and helps draw out the peaches' juices.
The step that matters
Securing the roll in the cloth. If the cloth is not moistened and floured, the dough can stick and tear, and a loose wrap lets the filling leak into the water. A snug, well-sealed roll keeps the peaches and juices inside while the dough steams and sets.
Swap the peach
How well each one fits the dish's main ingredients (flour, butter, sugar, milk, nutmeg):
- Vanillafits better
- Raisinfits better
- Figfits better
- Peachthe original
Fit is the average pairing score against flour, butter, sugar, milk, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
