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 ↓
Prune Pudding
Ingredients
Directions
The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Prepare the prunes
Rinse prunes in cold water.
Pour boiling water over the prunes.
Add sugar, lemon rind, and juice.
Cook gently for 4–5 hours in an earthen dish.
Make the batter
Melt butter in lukewarm scalded milk.
Add yeast cake, sugar, and salt.
When dissolved, add the beaten egg.
Stir in flour and mix thoroughly, then cover.
Let rise in a warm place (90°F) for 1 hour.
Stir the batter.
Bake and serve
Pour one third over the cooled prunes in a pudding dish.
Sprinkle with sugar and lemon rind, then cover.
Let rise for another hour.
Bake in a moderate oven (350°F) for 20–25 minutes, uncovered.
For the sauce, mix butter, flour, sugar, lemon juice, prune juice, and enough boiling water to make 1 cup, then boil.
Serve hot.
Pour remaining batter into patty pans and let rise.
Bake as well.

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
- Yeast cake
- Produces gas that makes the batter rise and become light.
- Egg
- Adds structure and richness to the batter as it sets.
- Flour
- Forms the batter's structure and, in the sauce, thickens when boiled.
- Butter
- Adds fat for richness and a tender crumb.
- Milk
- Adds moisture and softness to the batter.
- Prunes
- Provide the fruit base, with natural sweetness and moisture that soften during slow cooking.
The step that matters
Boil the sauce. Flour must reach a full boil to thicken the sauce and cook out its raw, pasty taste. Stopping early leaves the sauce thin and floury.

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