Green Pea Royale Soup

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 the base

  1. Mash the warm green peas to a pulp.

  2. Mix in the soup stock, corn starch, and beaten egg white until thoroughly combined.

Bake

  1. Spread the mixture in an earthenware pie plate.

  2. Place the pie plate in a pudding dish filled with hot water, ensuring the water touches the bottom of the plate.

  3. Cover and bake in a 400°F (200°C) oven until firm, about a few minutes.

Finish and serve

  1. Let it cool, then cut into diamonds or squares.

  2. Add the pieces to the hot soup three minutes before serving, ensuring the soup does not boil.

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

What each ingredient does

Green peas
Provide the main body and flavor of the soup base.
Egg white
Sets when baked, giving the mixture structure so it can be cut into firm pieces.
Corn starch
Thickens the mixture and helps it hold its shape when cooked.

The step that matters

Bake in a water bath. The hot water around the pie plate heats the mixture gently, so the egg white sets evenly without becoming rubbery or cracking. Baking it directly in dry heat risks overcooking the edges before the center firms.

Swap the peas

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

  1. Beansfits better
  2. Lima beansfits better
  3. Peanutfits better
  4. Peasthe original

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