What It Is and Which Form You Have
Tofu is made from soy milk and comes in textures ranging from silken to extra firm. Identify the form before following a recipe: related forms can differ in texture, concentration, heat tolerance or the job they do in a dish.
How to Choose It
Freezing tofu changes its texture and can make it firmer and more porous. Pressing medium through extra-firm tofu for at least 30 minutes removes water and helps it absorb marinades. Use these concrete cues at the shop and again before preparation. If a sealed product has no source-backed visual test, follow its label and reject damaged packaging rather than guessing from appearance alone.
How to Use It in Recipes
Opened uncooked tofu can be held in fresh water below 40 degrees Fahrenheit for three to four days. Silken tofu suits blending, while firmer tofu holds its shape better in cooked dishes. Let the intended technique decide the form. A finishing ingredient, a blended ingredient and one expected to hold its shape are not always interchangeable, even when their names are similar.
See Crispy Air Fryer Tofu with Soy Ginger Glaze for a concrete Recipe.net example. See Xi Shi Tofu Pudding for a concrete Recipe.net example. See Korean Braised Tofu Dubu Jorim for a concrete Recipe.net example. See Crispy Baked Tofu for a concrete Recipe.net example. These recipes contain an exact tofu match in their saved instructions, so they are practical next steps rather than loosely related recommendations.
How to Choose a Substitute
Choose a replacement by function, not by appearance alone. Unless the checked sources state a conversion, adjust cautiously and expect a change in flavour, texture or cooking behaviour instead of assuming a universal ratio.
How to Store It
Shelf-stable tofu can remain unopened for six to twelve months, but after opening it must be refrigerated. Opened tofu can be covered with fresh water in the refrigerator, changing the water daily, for up to five days; sour smell or sliminess are spoilage signs. Apply the instruction to the exact form and condition you have—whole, cut, opened, cooked or frozen. A storage window describes quality under the stated conditions; it never overrides clear signs of deterioration.
Common Mistakes to Avoid
The avoidable mistake is carrying one rule across every form. Keep the ingredient dry or cold where the evidence requires it, and treat an explicit safety instruction as more important than convenience.

Key Takeaways
- ✓ Read the recipe's full ingredient line before swapping tofu; the form and intended job matter.
- ✓ Store tofu according to its current condition—unopened, opened, cut or cooked—not by one blanket rule.
- ✓ Treat a missing ratio, temperature or storage period as unresolved instead of turning an estimate into a rule.
