Jelly Slices

Ingredients

Directions

Prepare the cake

  1. Bake a sheet of Genoise cake until it is less than 1 inch thick and level.

  2. Turn the cake out of the pan, bottom side up, and cut it into long strips.

  3. Split the strips and spread with red fruit jelly or jam.

Glaze and cut

  1. Prepare a pearl glaze by mixing powdered sugar with enough water or egg white to make a spreadable consistency.

  2. Add fruit juice to the glaze for a pink color if desired.

  3. Spread the glaze over the top of the jelly-covered strips.

  4. Cut the iced strips into long, narrow pieces using a knife dipped in hot water.

  5. Place the pieces on pans, spaced apart, to allow the icing to dry.

What each ingredient does

Genoise cake
Provides a light, sponge-like base that holds the jelly layer and glaze.
Red fruit jelly or jam
Adds sweetness and moisture and a fruity flavor between the cake and glaze.
Powdered sugar
Forms the sweet, spreadable glaze that sets into a smooth top layer.
Water or egg white
Thins the powdered sugar into a spreadable glaze that dries firm.

The step that matters

Cutting the iced strips. Dipping the knife in hot water and cutting cleanly keeps the glaze from cracking or dragging, so each piece keeps a neat edge and its layers stay distinct.
