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 ↓
Potatoes for Breakfast
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
Pare and slice the potatoes.
Boil the potatoes until tender.
Assemble
Layer the potatoes in a pan with a little butter, pepper, and salt.
Continue layering until the pan is full.
Pour in 1 cup of sweet cream.
Sprinkle a little flour over the top.
Bake
Bake at 350°F (175°C) until brown.

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 and absorbing the cream as they cook.
- Sweet cream
- Adds moisture and richness, and sets into a creamy custard-like texture as it bakes.
- Butter
- Adds fat and flavour to the layers and helps the top brown.
- Flour
- Sprinkled on top, it helps the surface brown and form a light crust.
The step that matters
Bake at 350°F (175°C) until brown. Baking too briefly leaves the cream unset and the potatoes firm, while over-baking can dry the top and scorch the surface. Checking for an even golden colour and tender potatoes shows the bake is done.

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