Jcing for Fruit Tarts, Puffs, or Pastry

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 glaze

  1. Beat the egg whites in a mug until solid froth forms.

  2. Spread some beaten egg white in the middle of the pie using a pastry brush.

  3. Sift plenty of powdered sugar over the egg white and press it down with your hand.

  4. Wash the brush and gradually add water until the sugar dissolves.

Bake and serve

  1. Place the pie in a 350°F (175°C) oven for 10 minutes.

  2. Serve cold.

What each ingredient does

Egg whites
Form a glossy, set coating that gives the pie a sheen when baked.
Pounded sugar
Adds sweetness and forms a crisp, dry layer over the egg white.

The step that matters

Beating the egg whites until solid froth forms. Egg whites need to be beaten enough to hold air and form a stable foam. Under-beaten whites run and soak in, while the foam helps the glaze stay in place and set evenly.
