Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Swiss Eggs

Oven, in the book's wordsA quick oven

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. Preheat the oven to 400°F (200°C).

  2. Spread the butter on a flat baking dish.

  3. Layer very thin slices of Gruyere cheese on the butter.

Assemble and bake

  1. Break the eggs on top of the cheese, keeping the yolks whole.

  2. Grate the remaining cheese and mix it with the parsley.

  3. Sprinkle the cheese and parsley mixture over the eggs.

  4. Bake in the oven for 5 to 7 minutes.

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

Eggs
Set into a firm, tender layer while keeping the yolks whole and runny.
Gruyere cheese
Melts into a savory base layer and browns on top when baked.
Butter
Adds richness and keeps the cheese and eggs from sticking to the dish.

The step that matters

Bake in the oven for 5 to 7 minutes. Eggs cook quickly once heated, so the whites set while the yolks stay soft. Checking early helps avoid overcooked, rubbery whites and a dry, chalky yolk.

Swap the parsley

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

  1. Nutmegfits about as well
  2. Parsleythe original
  3. Thymefits about as well
  4. Tarragonfits less well

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