Steamed Strawberry Marble Cake

This is a very soft, spongy & tasty cake. I would recommend this recipe, if you have leftover egg whites. I would double the recipe if I make this again next time for a thicker cake.

(Makes 6-7" round tin)
INGREDIENTS:
150ml Egg Whites

¼ tsp Cream of Tartar

100g Castor Sugar
½ tsp Vanilla Essence
125g Superfine Flour
½ tbsp Ovalette
50g Cooking Oil
1-2 tbsp Strawberry Emulco

METHOD:
1. Beat egg whites and cream of tartar until fluffy & thick.
Add in sugar gradually & beat until stiff.
Beat in flour & ovalette.
Finally, pour in oil & mix well.

2. Divide into two parts & add strawberry emulco to one.
Pour alternately into a lined & greased tin.
Steam for 40 minutes.
