Why it works: Potato and nutmeg are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 1,052 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Duchesse Potatoes

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the potatoes

  1. Boil the potatoes until tender.

  2. Mash them through a fine colander.

  3. Mix in the butter, salt, white pepper, nutmeg, and the yolks of the eggs.

Shape and bake

  1. Shape the potato mixture into small cakes, about 2 inches long and 1 inch wide.

  2. Place the cakes on a buttered baking sheet.

  3. Brush the tops with egg white.

  4. Bake in a moderate oven at 350°F (175°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 main body of the cakes, giving a soft, starchy texture once mashed.
Butter
Adds fat and richness, softening the mash and carrying flavor.
Eggs
Yolks enrich and bind the mash; whites brushed on the tops help them brown.

The step that matters

Mash the potatoes through a fine colander. Pushing cooked potatoes through a fine sieve breaks them into smooth, fine particles without releasing much starch, so the mash stays light and free of lumps. Overworking or using a coarse mash makes it gluey or grainy.

Swap the white pepper

How well each one fits the dish's main ingredients (potato, butter, egg, nutmeg):

  1. Cinnamonfits better
  2. Parsleyfits better
  3. Thymefits better
  4. White pepperthe original

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