In Chinese cooking, smoked tofu is a block of extra-firm tofu that has a smoky taste and is lightly seasoned. I used liquid smoke and black tea powder to mimic the smoky flavor, which makes it taste much better than the store-bought version. You can use it in dishes with tofu, but I prefer to serve it on rice or noodle bowls. For this recipe, you have the option of making it in an oven or an air fryer.
