Tofu should ideally be stored in an airtight container, either glass or BPA-free plastic, submerged in fresh water, and refrigerated. Change the water daily to maintain freshness.
Tofu is a delicate food that readily absorbs flavors and odors. Proper storage is crucial to maintain its quality and prevent spoilage. Whether you choose glass or BPA-free plastic, the most important factor is that the container is airtight. This prevents the tofu from drying out and absorbing unwanted smells from the refrigerator. Submerging the tofu in fresh water helps to keep it moist and prevents it from becoming slimy. Changing the water daily is essential because the water will absorb some of the tofu's flavor and can become cloudy over time. Using fresh water ensures the tofu retains its best possible taste and texture. Both glass and BPA-free plastic are suitable options. Glass is non-reactive and easy to clean, while BPA-free plastic eliminates concerns about harmful chemicals leaching into the tofu.
If you're not planning to use the tofu within a few days, consider freezing it. Freezing changes the texture of tofu, making it chewier and more absorbent, which can be desirable for certain recipes like stir-fries or marinades. Just be sure to press out the excess water after thawing.
