Swiss Rolls

Ingredient

* 3 eggs
* 2 drops of vanilla essence
* 110 grams / 3½ oz of castor sugar
* 75 grams / 2½ oz of flour
* 2 to 3 tablespoons of raspberry jam
* ¼ cup of icing sugar

Preheat the oven to 210°C, 410°F or gas mark 6½. Grease and line a swiss roll tin with cooking paper. Whisk the eggs, vanilla and sugar with an electric mixer or beater on high until the mixture resembles a thick stable foam, and the mark from a spoon dragged through the mixture doesn't disappear. Sift in the flour, and very gently fold the flour in with a large metal spoon. Gently pour the mixture into the prepared tin and smooth out to the corners with a pallet knife.

Bake for 8 to 10minutes. Check the sponge is cooked by carefully running your hand over the top. It is cooked if your hand leaves a slight mark, which disappears quickly and springs back. Turn out immediately onto a cake rack covered with a clean dry tea towel. Peel off the cooking paper and allow to cool. Spread the sponge lightly with raspberry jam and roll into a tight spiral with the aid of the tea towel, starting from the longer side. Remove the towel and sprinkle with icing sugar.
