I don't have a separate tofu presser. I remove the tofu from the box and discard the excess liquid. And place a heavy object on top and let it sit for 30 to 45 minutes. I then cut into cubes or bite-sized pieces.
In a saucepan, combine the soy sauce, rice vinegar, garlic, ginger, sugar, and 4 tbsps of water and let it simmer.
Meanwhile, mix the cornstarch in 2 tbsps of water. When the soy sauce mixture simmers, add this cornstarch slurry and cook until the sauce thickens. Then turn off the heat. The teriyaki sauce is now ready. Let it cool.
I added my tofu cubes directly in the saucepan with teriyaki sauce and let it marinate for 30 minutes. The sauce is sufficient for 16 oz tofu block as well.
Line a baking tray with food-grade aluminum foil and grease with oil lightly. Place the marinated tofu on the tray.
Preheat the oven in the high-broil mode. Broil the marinated tofu for 6 minutes on each side till it becomes firm and crispy. Sprinkle the toasted sesame seeds on top and serve warm.
Notes
Instead of rice vinegar, you can use mirin. In that case, reduce the sugar amount to 3 tbsps.
I recommend brown sugar, but you can use your choice and adjust it according to your preference.
Ginger and garlic add a subtle flavor, and I went with an equal amount, as suggested in the original recipe. But adjust the proportion according to your taste.
Marinate the tofu for a minimum of 30 minutes, but you can marinate up to 8 hours.
Do not broil the tofu for more than 15 minutes. Please check the post if your oven doesn't have a broil option.
