Technique Tip for This Recipe
When preparing tofu, it's essential to press it before cooking to remove excess moisture. This helps the tofu achieve a better texture and allows it to absorb more flavors. To press tofu, place it between two plates and put a heavy object on top, like a can or a book, for about 15-20 minutes. This step ensures your tofu will be crispy and delicious when cooked.
