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 ↓
Escalloped Potatoes
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the potatoes
Slice the potatoes thinly.
Soak the slices in cold water for 30 minutes.
Drain the slices.
Assemble and cook
Place them in a pudding dish.
Add milk, salt, and pepper to the dish.
Let the dish sit on the back of the stove until the potatoes are soft.
Add butter cut into small pieces on top of the potatoes.
Bake
Bake in a preheated oven at 400°F (200°C) for 15 minutes until browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the dish and set into tender layers as they cook in the milk.
- Milk
- Provides liquid that cooks into a creamy sauce coating the potato slices.
- Butter
- Adds richness and fat that helps the top brown during baking.
The step that matters
Let the dish sit on the back of the stove until the potatoes are soft. The short bake only browns the top, so the potatoes need to be fully tender before they go into the oven. Starch in potato softens when heated in liquid, and raw slices stay firm and chewy if this step is rushed.
Swap the potato
How well each one fits the dish's main ingredients (milk, pepper, butter):
- Potatothe original
- Capsicumfits about as well
- Tomatofits less well
- Asparagusfits less well
Fit is the average pairing score against milk, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
