Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. 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.
Make the sauce
Melt the butter in a saucepan.
Stir in the flour and thin with cream and stock; cook for five minutes.
Pour the mixture into the beaten eggs and add cheese; season with salt and pepper.
Assemble and bake
In a buttered baking dish, layer a little of the mixture, then sliced potatoes, and repeat until the dish is filled.
Sprinkle buttered crumbs on top.
Bake at 400°F (200°C) until brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the cream and stock into a smooth sauce that holds the potatoes together.
- Eggs
- Set when baked, binding the sauce so it turns firm and sliceable rather than runny.
- Cream
- Adds richness and moisture, keeping the sauce silky and the potatoes tender.
- Potatoes
- Form the bulk of the dish, soaking up the sauce while staying tender under the browned top.
- Butter
- Adds fat and flavour to the sauce and crumbs, helping the top brown.
The step that matters
Pouring the hot sauce into the beaten eggs. If the sauce is too hot when added, the eggs can scramble into lumps. Let it cool slightly and pour in gradually while whisking so the eggs thicken the custard smoothly.
Swap the potato

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