Rich in complete plant-based protein containing all nine essential amino acids; also provides iron, calcium (when coagulated with calcium-based agents), and isoflavones. Low in saturated fat and contains no cholesterol.

About

Tofu is a curd made by coagulating soy milk and pressing the resulting solids into blocks, originating in East Asia approximately 2,000 years ago. Firm and extra-firm varieties are produced by reducing the moisture content during pressing, resulting in denser, more compact curds with a crumbly, slightly chewy texture. These varieties retain approximately 10–15% moisture content and have a neutral, mildly nutty flavor that readily absorbs surrounding flavors. The production process involves soaking and grinding dried soybeans, boiling the resulting slurry, filtering out solids, adding coagulant (traditionally nigari or gypsum), and pressing the curds to the desired firmness.

Culinary Uses

Firm and extra-firm tofu are favored in applications requiring structural integrity and quick cooking. They are ideally suited for stir-frying, pan-frying, grilling, and baking, where maintaining a defined shape during high-heat cooking is essential. These varieties appear frequently in East and Southeast Asian cuisines, particularly in Chinese ma po tofu, Japanese agedashi tofu, Korean tofu grilled dishes, and Vietnamese stir-fries. They may be cubed, sliced, pressed to remove additional moisture, marinated for flavor absorption, or crumbled for textural variety. Their ability to develop a golden, slightly crispy exterior when pan-fried makes them suitable for both savory and umami-forward applications.

Forms & Preparations

Block — Standard pressed rectangular form, typically 14–16 oz per package; used whole, sliced, cubed, or cut into custom shapes for cooking applications.
Cubed — Pre-cut into uniform dice, convenient for stir-frying and marinating, though more prone to breaking apart during cooking if not handled carefully.
Pressed/Drained — Additional moisture removed via weight or commercial pressing before sale; concentrates texture further and accelerates absorption of marinades and seasonings.
Crumbled — Hand-crumbled or mechanically broken into irregular small pieces; mimics ground meat texture and used in applications like tofu scrambles, fillings, and tacos.
Sliced — Cut into thin to medium planks; ideal for pan-frying, grilling, and layering in composed dishes; develops crispy exterior when cooked over high heat.
Fried (ready-to-eat) — Pre-fried until exterior is golden and slightly crispy; sold as pouches or cakes and used directly in soups, stir-fries, and braised dishes without additional frying.
