You may fry the cubed tofu right away, in a medium sized skillet put a 1 tbsp of sesame oil over medium heat , fry them for about 5 minutes until golden brown. or of you may bake them first before frying to make it more crispy. If you want to bake it first, preheat oven to 400 degrees F (204 C) Place on a parchment-lined baking sheet and arrange in a single layer. Bake for 25 minutes to dry/firm the tofu. Once baked, remove from oven then fry afterwards.
