Lemon Puffs

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

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

  2. Beat the egg yolks, flour, sugar, and grated lemon rind together until well combined.

Make the custard

  1. Add the lemon juice and mix well.

  2. When ready to bake, stir in the milk.

Ice and bake

  1. In a separate bowl, beat the egg whites until frothy, then add the teacup of sugar.

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

  3. Spread the icing over the baked custard and let it brown slowly in the oven.

  4. Allow to cool before serving.

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

What each ingredient does

Eggs
Yolks thicken the custard and set it, while whipped whites give the icing lightness.
Milk
Provides the liquid base that gives the custard its soft, creamy texture.
Sugar
Sweetens the custard and icing, and helps the icing take on color as it browns.
Flour
Adds structure that helps the custard hold its shape as it bakes.
Lemons
Juice adds acidity and sharp flavor, while the grated rind adds aroma.

The step that matters

Let the icing brown slowly. Sugar-rich egg white topping can scorch quickly in a hot oven, so slow browning gives an even golden top without burning before the custard underneath is set.

Swap the lemon

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