Margherita Lemon 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. Beat the whites of 2 eggs and the yolks of 5 eggs until light.

  3. Add the sugar and pour in the scalding hot milk.

  4. Stir in the grated lemon peel.

Bake and finish

  1. Pour the mixture into a buttered pudding dish and place it in a pan of hot water.

  2. Bake until the custard is set.

  3. Spread a meringue made from the reserved egg whites beaten stiff with a little powdered sugar on top.

  4. Close the oven door and cook the meringue until slightly tinged with yellow-brown.

  5. Serve cold.

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

What each ingredient does

Eggs
Yolks and whites set the custard and the whites form the meringue topping.
Milk
Provides the liquid base that sets into a soft, creamy custard.
White sugar
Sweetens the custard and helps the meringue stay stable when beaten.
Lemon peel
Adds bright citrus aroma and flavor to the custard.

The step that matters

Baking the custard in a water bath. Gentle, indirect heat from the hot water keeps the custard's egg proteins from overcooking, which would make it grainy or watery. Remove it once just set, since residual heat keeps cooking it.

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