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 ↓

Ingredients
Directions
The book says “a steady oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Butter the bottom and sides of a tin basin.
Layer and bake
Layer sliced cold boiled potatoes in the basin, seasoning with butter, pepper, and salt.
Dust flour over each layer.
Repeat layering until the dish is filled.
Top with a layer of cracker crumbs.
Pour 1 cup of cream over the entire dish.
Bake for 30 minutes.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Potatoes
- Form the bulk of the dish, becoming tender as they bake in the cream.
- Flour
- Thickens the cream so the layers set into a cohesive, sliceable gratin.
- Cream
- Provides moisture and richness that cook down around the potatoes.
- Cracker crumbs
- Add a crisp, golden topping as they toast in the oven.
- Butter
- Adds fat and richness, and helps the surface brown.
The step that matters
Pouring the cream over the whole dish. The cream must reach down through every layer so the potatoes cook evenly and the flour can thicken the liquid. Pouring only on top leaves the lower layers dry and under-set.
Swap the potato
How well each one fits the dish's main ingredients (butter, pepper, flour, cream):
- Spinachfits about as well
- Leekfits about as well
- Potatothe original
- Chivefits about as well
Fit is the average pairing score against butter, pepper, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
