Tofu, a versatile soy-based protein, is a cornerstone in many culinary traditions, offering a neutral canvas for absorbing diverse flavors. Mastering its proper storage is essential for preserving its fresh taste, firm texture, and nutritional integrity, ensuring it remains a delightful and healthy component in your meals.
Storage Time
Unopened, shelf-stable tofu can last for several months in the pantry, typically until the 'best by' date. Once opened, or for refrigerated tofu, it should be consumed within 3–5 days when stored in the fridge. For longer preservation, tofu can be safely frozen for up to 3–5 months.
Temperature
Always keep opened or refrigerated tofu submerged in fresh water in an airtight container in the refrigerator, maintaining a consistent temperature between 0–4°C (32–40°F) to significantly slow bacterial growth and maintain optimal freshness.
Freezing
Yes, tofu freezes remarkably well, though it will undergo a textural transformation, becoming firmer, chewier, and more porous, which can enhance its ability to absorb marinades. To freeze, first drain the tofu block thoroughly and press out as much excess water as possible. Cut the tofu into your desired portions (cubes, slices, or crumbles). For best results, flash freeze the pieces in a single layer on a parchment-lined baking sheet until solid, then transfer them to an airtight freezer-safe bag or container, removing as much air as possible. Thaw frozen tofu overnight in the refrigerator or by submerging the sealed bag in a bowl of cold water; gently squeeze out any remaining water before cooking to achieve a fantastic, meat-like texture.
Signs of Spoilage
- A distinct sour, yeasty, or off-putting smell, which is a clear departure from its usual mild or neutral aroma.
- The surface of the tofu developing a slimy, sticky, or unusually slick texture, indicating bacterial growth.
- Any visible discoloration, such as a yellowish, pinkish, or greenish tint, or the appearance of fuzzy mold spots on the tofu block.
