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
Cook, drain, and mash the potatoes, then pass them through a fine sieve.
In a saucepan, combine the mashed potatoes, butter, whole eggs, egg yolks, salt, and pepper.
Butter a 2-quart mold and sprinkle it with fresh bread crumbs.
Bake and serve
Fill the mold with the potato mixture, top with more bread crumbs and bits of butter.
Bake in a 350°F (175°C) oven for 30 minutes.
Before serving, run a knife between the potatoes and the mold, carefully turn it over, and remove the mold.

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 timbale and give it a soft, starchy body.
- Butter
- Adds richness and moisture to the potato mixture and helps the surface brown.
- Whole eggs
- Bind the mashed potatoes so the timbale holds its shape when baked and turned out.
- Egg yolks
- Add richness and firm the custard-like mixture as it sets in the oven.
The step that matters
Turning out the timbale. Run the knife fully around the edge before inverting so the baked potato releases cleanly from the mold. Sticking at the edges can tear the shape, since the mixture is soft and set only by the eggs.
Swap the potato
How well each one fits the dish's main ingredients (butter, egg, pepper, bread):
- Capsicumfits better
- Asparagusfits better
- Chivefits about as well
- Potatothe original
Fit is the average pairing score against butter, egg, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
