Directions

1. First, prepare the syrup: mix sugar and water in a saucepan and bring to a boil. Let cool. Add the strawberry (or grenadine) syrup.
2. When you start preparing the sponge cake, preheat oven to 400/425 degrees Fahrenheit.
3. Place the eggs and sugar in a medium-sized bowl over a double boiler. Keep the water just to a simmer, do not boil. Using an electric whisk, beat the eggs and sugar mixture on medium speed for 5 to 10 minutes. The mixture should double in volume, be pale yellow, and reach the ribbon stage (this means that when you lift the whisk ove the mixture, the batter should fall slowly forming a ribbon that will briefly hold its shape).
