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 ↓
Apple or Fruit Cups
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the batter
Preheat oven to 350°F (175°C).
Sift together flour, salt, sugar, and baking powder.
Beat the egg, add the milk, and stir into the dry mixture, adding more milk to make a thick batter.
Add the melted butter and mix well.
Fill and cook
Butter baking cups and fill each with a spoonful of batter.
Place a quarter of a tart apple on top and cover with more batter, filling the cup two-thirds full.
Steam or bake until cooked through and serve with hard sauce.

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
- All-purpose flour
- Provides the main structure of the batter as it sets during cooking.
- Egg
- Binds the batter and adds structure and richness to the cups.
- Baking powder
- Releases gas during cooking so the cups rise and stay light.
- Butter
- Adds fat for tenderness and flavor in the batter.
- Tart apple
- Adds moisture and a tangy flavor that contrasts with the sweet batter.
The step that matters
Filling the cups two-thirds full. Batter rises as it cooks and can overflow or turn dense if the cup is overfilled or underfilled. Leaving room for rising lets the cups bake evenly and hold their shape.
Swap the apple
How well each one fits the dish's main ingredients (flour, sugar, egg, milk, butter):
- Vanillafits better
- Raisinfits better
- Figfits better
- Applethe original
Fit is the average pairing score against flour, sugar, egg, milk, butter. Candidates are from the same food group and used in at least 100 recipes.
“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.
