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.

Make the custard

  1. In a bowl, beat the eggs and sugar together until well combined.

  2. Add the sweet milk and corn starch, mixing until smooth.

Bake

  1. Flavor as desired, then pour into a baking dish.

  2. Bake in a moderate oven at 350°F (175°C) until set.

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

What each ingredient does

Eggs
Set the custard as they coagulate during baking, giving it structure.
Sugar
Adds sweetness and helps the eggs blend smoothly into the custard.
Sweet milk
Provides the liquid base and moisture that the eggs set within.
Corn starch
Thickens the liquid so the custard holds together and becomes smooth.

The step that matters

Bake until set. Egg proteins set with heat, so the custard should be baked until just firm. Overbaking causes it to curdle and weep, leaving a grainy, watery texture.
