"If anything, tofu is white, where does the color say?" Indeed, its place of origin is in our neighboring countries. It's not a mystery at all. It's not their new technology product. It's changing the formula and adding some raw materials so that the tofu produced will not only change color, but also its taste and nutrients. It is much higher than traditional white bean curd. In a nutshell, colored tofu is a combination of soy milk and other beans or vegetables. For example, green tofu, with green beans. If you use red beans, the finished product will be red. If peppers or carrots are used instead, the product will be bright red or yellow in the red. If you put on a pumpkin, it is pure yellow. Look, recipes are so simple.
