Priyanka Naik emphasizes the importance of preparing tofu properly to achieve an optimal grilling experience: 'First drain and press your tofu, freeze overnight, completely thaw, and then marinate. This helps create a more 'meat-like' texture and makes it easy to grill or fry.' The process of freezing tofu alters its texture significantly, making it less watery and more absorbent for marinades, resulting in tastier dishes.
