Thousand-layer tofu can generally be used after blanching. Blanching water can remove the odor and impurities of tofu and improve the taste of tofu. You can choose to put it in the refrigerator after blanching. Cold storage can prolong the shelf life of tofu and keep its freshness. Put the blanched thousand-layer tofu in a sealed container or fresh-keeping bag, and then put it in the refrigerator for preservation. Please ensure that the storage container is well sealed to prevent the smell from spreading.
