A snack with friends? Bring a chocolate roll to the table: an original, fun way to share a classic, quick to prepare dessert. This soft spiral of sponge is ready in less than half an hour. It is filled with a chocolate cream that gives the roll just the right softness. Simply looking at it makes your mouth water! Sponge is a basic recipe used in confectionery. You can use ready-made sponge if you like, but the recipe is really simple: you just have to pay attention to the cooking time, and browning the surface just right. Once ready, keep the chocolate roll at room temperature in a dry place, covered with a cloth.
To prepare a chocolate roll, start with the sponge: whisk egg yolks in a bowl with water, honey, 30 g / 1 oz of sugar, lemon peel and vanilla. Whisk egg whites with remaining sugar in a separate bowl. Fold second mixture into first, and add flour gradually.
Spread a non-stick silicone baking mat out on a table top. This material slows down heat conduction. Spread mixture on top.
Bake for five minutes at 240 °C / 464 °F. When done, the sponge should be golden brown on the surface.
Spread chocolate cream on sponge and roll up.
Slice chocolate roll, and serve cake spirals with a little delicious dark chocolate cream if you wish. Sprinkle with powdered sugar to taste.
