Watermelon cake rolls

The theme of the competition, “Creating with natural materials”, is very much appreciated to make baking both fun and healthy. As soon as they enter the market, their eyes are focused on the “coloured” food. There's all kinds of food in the kitchen, and there's a very colorful man! Almost all kinds of vegetables have been rolled over, poor ass, looking at fruit. I'm surprised to see that the fruit is baked, and it's much better than the vegetable juice, which not only is colorful, but also tastes so much more. For the first time, you tried to make a dye with Yang Mei's juice, while Yang Mei mitigated the butter, the cream reduced the sourness of Yang Mei, and the sweetness and sour taste were just as good as Mom said. This cake looks complicated, but if you can make cake rolls and mousses, then this watermelon roll is totally hard on you. It's a mousse cake made of Yang Mei juice, which tastes slightly sour, and tastes more sweet than ordinary moose. One of them can be made of fake melons with black sesame dots, and you can switch to chocolate particles. The green melons are spinach juice rolls, soft and soft, and Moose's sweet and twigs are mixed, making it impossible to stop。
