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 ↓
Potato Mould
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.
Mash the potatoes in the usual way.
Press the mashed potatoes lightly into a well-buttered mould.
Turn the mould out and brown it evenly in the oven at 400°F (200°C) or before the fire.
If desired, sprinkle brown bread raspings inside the mould before adding the potatoes.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Mashed and pressed together, they form the body and structure that holds the mould's shape.
- Butter
- Greasing the mould helps the potato release cleanly and adds richness and browning on the surface.
The step that matters
Press the mashed potatoes lightly into the mould. Mashed potato is rich in starch, and overworking or packing it too hard makes it dense and gluey. Light pressing keeps it tender and airy while still holding the shape when turned out.
Swap the potato
How well each one fits the dish's main ingredients (butter, bread):

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