Firm tofu is sold in a block and can be sliced or diced to be pan-fried and used in a range of recipes from salads to stir fries. Shallow-frying tofu is ideal for creating a crisp texture on the outside of the tofu whilst keeping a softer texture on the inside. Shallow-frying uses less oil than deep-frying. Whenever using tofu, remember to rinse and dry the block of tofu before cooking.
