Milk Soup with Egg

Ingredients

Directions

The book gives no oven temperature. The 170°F (77°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the thickener

  1. Mix corn starch, arrowroot, or flour with cold water in a bowl.

  2. Add a little salt and the egg yolks, then beat with an egg beater.

Make the soup

  1. In a pot, combine fresh milk and water, and heat to about 170°F (77°C).

  2. Stir in the flour and egg mixture, along with lemon rind, vanilla bean, or bitter almond.

  3. Stir continuously or beat with an egg beater until it comes to a boil.

  4. If using skim milk, add butter.

  5. If desired, add sugar, honey, or condensed milk for sweetness.

Serve

  1. For a cold soup, stir after removing from heat until nearly cold.

  2. Serve with crackers, toast, or strawberries.

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

What each ingredient does

Corn starch, arrowroot, or flour
Thickens the milk into a smooth, soupy texture as it heats.
Egg yolks
Add richness and help enrich the soup's texture and body.
Fresh milk
Forms the base of the soup and provides creaminess and body.

The step that matters

Bringing the soup to a boil while stirring. Starch thickens as it heats, but the egg yolks can curdle or turn grainy if overheated or left unstirred. Constant stirring keeps heat even and the texture smooth.

Swap the lemon

The recipe marks lemon as optional. How well each one fits the dish's main ingredients (corn, egg, milk, vanilla, sugar, butter):

  1. Coconutfits better
  2. Figfits better
  3. Peachfits better
  4. Lemonthe original

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