1.25ml (1/4 tsp) Vanilla extract
2g Lemon juice
65g (5 tbsp) Sugar
100g Mascarpone cheese
18g (1.5 tbsp) Sugar
1.25ml (1/4 tsp) Vanilla extract

* Important tips:
1. If you don't like vanilla extract, you can omit it.
2. The main reason for the skin to fall off is not baked through, the surface is too wet so the skin will fall off when rolled later. To avoid falling off, you can increase the baking time, or bake at high temperature for 10 more minutes. If your oven has a fan function, please use the fan function to bake, so the surface is easy to dry.
3. There are two reasons for the cracking: one is that the egg whites are too dry, and the second reason is that the baking temperature is too high. Therefore, when whipping the egg whites, try to whip them a little soft, wet foam, and the whisk is a big hook. Because this baking pan is relatively large, so the chance of cracking is very small, you can use a relatively high temperature to bake.
4. Do not wait for the roll to cool down before rolling, when the temperature of the cake roll is close to hand temperature you can do, it is easier to crack the roll after it cools down
5. If you don't have mascarpone cheese, you can use cream cheese instead!
6. Refrigerate for about 1 hour then to cut and enjoy!
