Milk Soup

Ingredients

Directions

Make the milk

  1. Boil the milk with salt, cinnamon, and sugar.

  2. Optionally, stir blanched almonds into the boiling milk before pouring.

Thicken and serve

  1. Lay toasted bread slices in a tureen and pour hot milk over them to soak.

  2. Beat the egg yolks and gradually add them to the milk, stirring over heat until thickened.

  3. Remove from heat immediately to prevent curdling and pour over the soaked bread.

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.

Cinnamon and sugar barely smell alike, yet cooks put them together in 30,779 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

Milk
Forms the liquid base that the yolks thicken into a custard.
Egg yolks
Thicken the milk into a custard as they gently set with heat.
Toasted bread
Soaks up the hot custard, giving the soup a soft, bready body.
Sugar
Adds sweetness to the milk.

The step that matters

Removing the milk from heat once the yolks are added. Egg yolks set at a fairly low temperature, and if the custard gets too hot or keeps cooking, the proteins tighten and curdle. Taking it off the heat as soon as it thickens keeps it smooth.

Swap the almond

The recipe marks almond as optional. How well each one fits the dish's main ingredients (milk, cinnamon, sugar, bread, egg):

  1. Almondthe original
  2. Pecansfits about as well
  3. Chestnutfits less well
  4. Walnutfits less well

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