There are two types of tofu, firm and soft or ‘silken’.
Soft tofu is not pressed and therefore is has a spongy, cotton texture hence the name silken. Soft tofu is not normally cooked, rather seasoned with savoury flavours such as soy, ginger and spring onion or sweetened and served as a dessert.
Firm tofu is much more resilient as the liquid has been pressed out of it making it suitable for cooking. If you prefer a firmer tofu try pressing it further at home by placing a (clingfilmed) heavy book on top for a few hours. Tofu is great when baked, scrambled, dusted with corn flour and fried or even used in Miso soup. It can be used as a meat substitute or as an accompaniment as in Peter Gordon’s Pork belly, kimchi, smoked tofu, shiitake and peanuts.
Freezing tofu creates cavities in the curd enabling flavours to be absorbed more easily. ‘Thousand Layer Tofu’ is tofu that has been frozen, then thawed as the holes look like layers.
