Elegant And Easy Swiss Roll Cake

Makes 9 servings

Ingredients:

3 large or extra large eggs (I like Egglands Best )
1/2 super fine sugar or caster sugar. (Domino makes this and you must use super fine sugar for this recipe. You can also use it for any recipe that calls for granulated sugar. It is not powdered sugar.)
6 -7 tbsp all fruit peach, strawberry, raspberry jams (or any all fruit jam you like. Polaner has a large variety)
1 1/2 tsp fresh lemon juice
Pinch salt
3/4 tsp vanilla extract
About 1 tbsp boiling water
2 tbsp super fine sugar
3/4 cup sifted all purpose flour
For decoration:

2 tsp powdered sugar
1/2 tsp skim milk, more or less, to make easy to pour over cake.
Drizzle of melted chocolate over the top, this is optional
