The most common way to preserve frozen tofu is to keep it in a frozen place in the refrigerator. Some families will buy frozen tofu home, soak it in water, and then store it in the refrigerator when preserving stewed tofu.

Another method is to melt the frozen tofu with flowing water, and then put the tofu in the frozen layer of the refrigerator, and then store it after freezing into frozen tofu. This method can prolong the storage time of frozen tofu and retain the nutrition in tofu.
