Ingredients for the sponge: 4 eggs / 80g sugar / 67g plain flour
Method: Place the eggs and vanilla extract into a bowl. Gradually add in sugar and whisk until pale and thickened. Sift the flour into the bowl and fold together. Pour the sponge mixture into a baking tray with baking paper and bake for 10 minutes at 200'C preheated oven. Place the cooked sponge on a wire rack and place the sponge together with the wire rack into a plastic bag for cooling down. This is to keep the sponge moisture and much easier to roll up.
Ingredients for the fresh custard: 2 egg yolks / 133ml milk / 40g sugar / 13g flour / 1 tsp vanilla extract / 6g butter / 2 tsp Rum (optional)
Method: Mix the egg yolks with two teaspoon of milk in a bowl until well combined. Then, mix in the flour and make sure there is no lumps. Place the milk in a saucepan with vanilla extract and sugar, bring to the boil. Once the sugar dissolve in the milk, gradually pour onto the eggs mixture and stir then pour back into the pan. Return to the heat and using a whisk, lightly stir the mixture to thicken, do not boil. As the egg yolks warm, it will thicken to create custard. Keep stirring until it coats the back of the spoon. Remove from the heat and keep stirring and add in the butter. When the custard slightly warm add in rum. Pour the custard into a shallow bowl and cover with cling wrap. Place it into the fridge when it completely cool down and ready to use.

- Roll up the sponge with cling wrap and chilled in the fridge.
- Cut the roll with a serrated knife into 8 thick portions.
