firm or extra firm tofu - 1 block

OtherYear-round. Tofu is a shelf-stable, industrially produced ingredient available consistently throughout the year in most markets worldwide.

Rich in complete protein containing all nine essential amino acids, with approximately 8-15 grams per 3.5-ounce serving depending on firmness. Good source of iron and manganese, and typically fortified with calcium in commercial production.

About

Tofu is a curd-based food produced by coagulating soy milk in a process similar to cheese-making, with its origins in China dating back to approximately the 2nd century BCE. The coagulant (traditionally nigari, gypsum, or modern glucono delta-lactone) causes soy protein and fats to separate from liquid whey. Firm and extra-firm varieties contain less water content than silken tofu, resulting in a denser, more cohesive texture with a slightly grainy structure. The flavor is mild and subtly nutty, serving as a neutral vehicle for absorbing surrounding seasonings and sauces. Firmness levels are determined by the percentage of water content and pressing duration during manufacturing.

Extra-firm tofu is more densely compressed than firm tofu, making it the preferred choice for grilling, pan-frying, and stir-frying applications where structural integrity is essential. Both varieties maintain their shape during high-heat cooking and can develop crispy surfaces while retaining a tender interior.

Culinary Uses

Firm and extra-firm tofu are essential ingredients in East and Southeast Asian cuisines, particularly in Chinese, Japanese, Korean, and Vietnamese cooking. These varieties excel in applications requiring heat resistance and textural contrast: stir-fries, grilling, deep-frying, braising, and pan-searing. The dense structure allows for browning and crisping, making it ideal for achieving caramelized exteriors. Extra-firm tofu is particularly valued for Korean soon-tofu stews, mapo tofu (Chinese), and Japanese agedashi tofu. In Western vegetarian and vegan cooking, these firmer varieties serve as protein-rich meat alternatives in dishes like tofu scrambles, satay skewers, and Buddha bowls. Proper pressing before cooking removes excess moisture, enhancing browning and sauce absorption.

Forms & Preparations

Block (unpressed) — Whole curd block in original packaging with water; requires pressing to remove moisture before cooking.
Pressed block — Water removed via weight or mechanical pressing; ready for high-heat cooking, slicing, or cubing for maximum browning.
Cubed — Cut into small dice before pressing; commonly used for stir-fries and maintains even cooking.
Sliced — Cut into thin to thick planks; ideal for grilling, pan-frying, and breading or marinating.
Crumbled — Hand-broken into small irregular pieces; mimics ground meat texture for scrambles, tacos, and meat-based dishes.
Frozen and thawed — Freezing creates ice crystals that are removed upon thawing, resulting in spongier texture ideal for absorbing marinades and braising liquids.
