Frosted Custard

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the custard

  1. Preheat the oven to 350°F (175°C).

  2. In a bowl, mix the flour and sugar together.

  3. In a saucepan, combine the milk, eggs, flour, sugar, salt, and nutmeg.

  4. Cook over medium heat, stirring constantly until thickened.

Bake and frost

  1. Pour the mixture into a baking dish and bake until set.

  2. For the frosting, beat the egg white until stiff peaks form, then gradually add 1 tablespoon of sugar.

  3. Spread the frosting over the custard and brown it in the oven.

Milk and flour barely smell alike, yet cooks put them together in 78,219 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

Eggs
Thicken the custard as they set when heated, giving it structure.
Milk
Forms the liquid base of the custard, providing moisture and a soft texture.
Flour
Stabilizes the custard during cooking so it thickens smoothly without curdling.
Sugar
Sweetens the custard and helps the egg white frosting become stable and glossy.
Egg white
Whipped to stiff peaks to form a light frosting that browns in the oven.

The step that matters

Cook the custard until thickened. Stirring constantly over medium heat keeps the eggs from scrambling or curdling while the starch and egg proteins thicken the milk. Undercooking leaves it runny and unable to set when baked, while overheating can make it grainy.

Swap the nutmeg

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

  1. Cinnamonfits better
  2. Nutmegthe original
  3. Jalapenofits less well
  4. Turmericfits less well

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