Baked 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, beat the eggs well without separating the whites and yolks.

  3. Add the sugar, milk, flavoring, and butter to the eggs and mix well.

Bake

  1. Pour the mixture into a baking dish and bake until solid, being careful not to overbake to avoid a spongy texture.

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.

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

What each ingredient does

Eggs
Their proteins set when heated, giving the custard its firm structure.
Milk
Provides the liquid base and milk proteins that keep the custard soft and creamy.
Sugar
Adds sweetness and slightly softens the set texture.
Butter
Adds fat for a richer mouthfeel.

The step that matters

Bake until solid, without overbaking. Egg proteins set as the custard heats. If it bakes too long, they tighten too far and squeeze out liquid, leaving a spongy, weeping texture instead of a smooth, tender set.
