Lemon Puffs

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the lemon base

  1. In a small saucepan, combine sweet milk, ground sugar, butter, grated lemon rind, and salt. Heat until boiling, ensuring the butter melts completely.

  2. Stir in flour with a wooden spoon until very smooth. Cook for 1 minute over heat.

  3. Remove from heat and beat in eggs one at a time until fully incorporated.

Shape and bake

  1. Roll out puff pastry trimmings to ⅛ inch thick and cut out 24 to 30 rounds using a 2‑inch cutter.

  2. Place rounds on a baking sheet, brush lightly with beaten egg, and add a teaspoon of the lemon mixture on each round.

  3. Fold the sides to form a three‑cornered hat shape, brush with egg, and bake at 400°F (200°C) until light brown.

Serve

  1. Serve hot on a folded napkin.

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

What each ingredient does

Eggs
Bind the batter and help the puffs set and rise in the oven.
Flour
Thickens the lemon base into a smooth paste that holds its shape.
Butter
Adds richness and tenderness to the lemon base.
Puff pastry trimmings
Form the crisp, flaky outer case that holds the lemon filling.

The step that matters

Beat in the eggs one at a time off the heat. Adding eggs to a very hot mixture all at once can scramble them. Beating them in gradually, off the heat, lets each egg blend into a smooth, glossy base that will set properly.

Swap the lemon

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