Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Hashed Potatoes with Cream
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the hashed potatoes
Combine the chopped potatoes, cream, salt, pepper, nutmeg, and butter in a saucepan.
Heat over medium heat until very hot, then serve immediately.
Make Delmonico potatoes
For Delmonico potatoes, transfer the mixture to a baking dish.
Dust with bread crumbs.
Bake at 400°F (200°C) until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the body of the dish, with starch that thickens the mixture as it heats.
- Cream
- Adds moisture and richness, giving the potatoes a soft, creamy texture.
- Butter
- Adds fat for richness and flavor, and helps the top brown in the oven.
The step that matters
Heating the cream and butter over medium heat. Cream and butter can scorch on the pan bottom or separate if the heat is too high. Gentle, even heat brings the mixture to very hot without breaking the emulsion, so the sauce stays smooth.
Swap the potato
How well each one fits the dish's main ingredients (cream, pepper, nutmeg, butter, bread):
- Spinachfits about as well
- Potatothe original
- Capsicumfits about as well
- Leekfits about as well
Fit is the average pairing score against cream, pepper, nutmeg, butter, bread. Candidates are from the same food group and used in at least 100 recipes.
