The preparation method of frozen tofu is as follows:

1, a piece of north tofu, that is, brine tofu, also known as old tofu, is generally used to make frozen tofu.

2. Soak it in light salt water, then bag it and freeze it until it turns pale yellow, usually for one night.

3. When eating, thaw before cooking. Frozen tofu can be used as stew or hot pot, both of which are delicious.
