Eggs Gratin

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the eggs

  1. Shell the hard‑boiled eggs and dice them.

Make the sauce

  1. In a saucepan, rub the butter with the flour.

  2. Add the milk and cream, then season with salt, pepper, and nutmeg.

  3. Stir until the mixture boils.

  4. Mix the diced eggs with the sauce.

Bake and serve

  1. Transfer to a baking dish and sprinkle grated cheese on top.

  2. Bake at 400°F (200°C) for 8 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
Provide the bulk and protein that give the gratin its body.
Butter
Adds fat and richness, and coats the flour to start the sauce.
Flour
Starch thickens the milk into a smooth, spoonable sauce when it boils.
Milk
Forms the liquid base of the sauce that binds the eggs together.
Cheese
Melts and browns on top, adding savory flavor and a golden crust.

The step that matters

Stir until the mixture boils. Flour starch only thickens fully once the sauce reaches a boil. Stopping early leaves the sauce thin and can leave a raw, floury taste.

Swap the nutmeg

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

  1. Nutmegthe original
  2. Parsleyfits about as well
  3. Cinnamonfits about as well
  4. Thymefits less well

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