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 ↓
Apple Dumplings
Ingredients
Directions
Prepare the apples and potatoes
Peel and core the apples, then cut them in half.
Mash the potatoes and sift them through a colander.
Make the dough
Add butter and salt to the mashed potatoes.
Stir in milk until the mixture is as stiff as pound cake.
Beat the egg white until light and mix it into the potato mixture.
Gradually add flour until the dough is firm enough to roll.
Form and cook the dumplings
Form the dumplings and place them in boiling water with plenty of space.
Cook for about 30 minutes, cutting larger apples into quarters and grouping them.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green apples
- Provide the fruit filling and a tart flavor that contrasts with the sweet dough.
- Potatoes
- Add starch and body to the dough, giving it a tender, moist texture.
- Butter
- Adds richness and fat, contributing flavor and a tender crumb to the dough.
- Milk
- Moistens the potato mixture so it can be brought together into a workable dough.
- Egg white
- Adds structure and lightness to the dough as it sets during cooking.
- All-purpose flour
- Builds the dough's structure, making it firm enough to roll and hold its shape.
The step that matters
Gradually add flour until the dough is firm enough to roll. Flour absorbs moisture and builds gluten and starch structure. Adding too much makes the dumplings dense and tough, while too little leaves them too soft to hold their shape in boiling water.
Swap the apple
How well each one fits the dish's main ingredients (potato, butter, milk, egg, flour):
