Potato Rolls

Why it works: Pepper and nutmeg match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 13,015 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

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.

Prepare

  1. In a bowl, combine the mashed potatoes, pepper, coarse sea salt, nutmeg, and egg yolk.

  2. Form the mixture into flat cakes.

  3. Place the cakes in a baking pan.

Bake

  1. Brush the tops with the egg white.

  2. Bake in a 400°F (200°C) oven until browned.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

    Shared aroma: (e)-2-octenal (fatty, green).

Nutmeg and egg barely smell alike, yet cooks put them together in 24,744 recipes: they work on texture and structure more than aroma.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Mashed potatoes
Form the body of the rolls and provide moisture and starch for a soft interior.
Egg yolk
Binds the potato mixture together and adds richness and colour.
Egg white
Brushed on top to help the surface brown and turn glossy in the oven.

The step that matters

Brush the tops with the egg white. A thin, even coat gives the surface its glossy, browned finish. Too much egg white can pool and make the bottoms soggy or the tops uneven.

Swap the potato

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

  1. Spinachfits better
  2. Capsicumfits better
  3. Sweet potatofits better
  4. Potatothe original

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