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.

Make the lemon filling

  1. Combine sugar, butter, 2 whole eggs, lemon juice, and grated lemon rind in a saucepan.

  2. Heat the mixture over low heat, stirring until it thickens to the consistency of honey.

  3. Remove from heat and let cool.

Assemble and bake

  1. Roll out the rich pastry and place it in a baking dish.

  2. Beat the reserved egg whites with 3 tablespoons of sugar until creamy.

  3. Spread the egg white mixture on top of the cooled lemon filling.

  4. Bake in a preheated oven at 350°F (175°C) until the top is slightly browned.

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

What each ingredient does

Eggs
Egg yolks and whole eggs thicken the lemon filling as it heats, while whites form the topping.
Butter
Adds richness and a smooth, tender texture to the lemon filling.
Sugar
Sweetens the filling and, when beaten with egg whites, gives the topping its body.
Lemon juice
Adds sharp acidity that balances the sweetness of the filling.

The step that matters

Heating the lemon filling. Cooking over low heat and stirring keeps the eggs from scrambling while the mixture thickens. If it gets too hot, the eggs can curdle and the filling becomes grainy instead of smooth.
