Tip: Super-firm tofu doesn’t need to be pressed. If you use extra-firm tofu, press and drain the excess water before crumbling. To press a block of tofu, wrap the block in a dish towel and place on a rimmed plate. Place a cast-iron skillet on top or other heavy object on top; let tofu drain for 20 minutes. This can be done up to 24 hours ahead of time.
