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 ↓
Timbale of Potatoes
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Boil, drain, wash, and pass the potatoes through a fine sieve.
In a saucepan, combine the potatoes with butter, whole eggs, egg yolks, salt, pepper, nutmeg, and sugar.
Butter a 2-quart copper timbale mold and sprinkle it with fresh bread crumbs.
Bake and serve
Pour the potato mixture into the mold and add bits of butter on top.
Bake in a moderate oven at 350°F (175°C) for 30 minutes.
Before serving, run a knife between the potatoes and the mold, then carefully turn it over to release.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Irish potatoes
- Form the bulk of the timbale, giving it body and a soft, moist texture once mashed.
- Butter
- Adds richness and moisture, and carries flavour through the custard-like potato mixture.
- Whole eggs
- Bind the potato mixture and set during baking so the timbale holds its shape.
- Egg yolks
- Add richness and help the mixture set into a smooth, tender structure.
The step that matters
Turning the timbale out of the mold. Eggs set as the timbale bakes, so the mixture can stick to the mold's sides. Running a knife around the edge first loosens it, helping the shape hold when inverted.
Swap the potato
How well each one fits the dish's main ingredients (butter, egg, pepper, nutmeg, sugar, bread):
- Capsicumfits better
- Sweet potatofits about as well
- Shallotfits about as well
- Potatothe original
Fit is the average pairing score against butter, egg, pepper, nutmeg, sugar, bread. Candidates are from the same food group and used in at least 100 recipes.
