Sponge Cake
- 1 tsp. lemon/orange rind
- 1 c. sugar, divided in halp
- 4 eggs
- 1 tbsp. lemon juice
- 2 tbsp water
- 1/2 tsp vanilla extract
- 1 c. (4 oz) cake flour, or remove 2 tbsp of a.p. flour and replace with 2 tbsp corn starch
- 3/4 tsp. baking powder
- 1/4 tsp salt
- 1/2 tsp cream of tartar
Pre-heat oven to 350° F. Mix together flour, baking powder, and salt, and set aside. Mix rind into half the sugar. Beat egg yolks, lemon juice, vanilla extract together, and then add sugar/rind mixture and beat until pale and fluffy. Clean beater thoroughly. In very clean bowl, beat egg whites for 30 seconds, then add cream of tartar. When soft peaks form, gradually add rest of sugar. Continue beating until stiff peaks form. Fold flour mixture into egg yolks, then slowly fold egg whites into batter.
Transfer to baking pan (ideally an ungreased angel food cake pan) and cook until a toothpick inserted into centre of cake comes out clean, about 30 minutes. Remove from oven and invert for at least one hour.
Serve with lots of fresh strawberries and whipping cream.
