Mix the soy milk and nigari. Microwave for 30 seconds.
Stir up the mixture from Step 1. Gently pour into the container in which you'd like to harden the tofu (make sure to use a microwave-safe container).
Microwave Step 2 for 3 minutes. Let it rest for 5 minutes. Microwave again for 2 minutes. Then finally, let it rest for 10 minutes.
This tofu is delicious warm or chilled. It's also tasty enough without any topping, but for best results please enjoy with your favorite topping and seasoning.
Story Behind this Recipe
I've had many failed trials with the tofu becoming too runny or bursting midway... So, I've finally managed to put this recipe together after many experiments.
Make sure not to cover the container with plastic wrap when microwaving the tofu. In Step 3: When you are letting the tofu rest for 5 minutes and then for 10 minutes, leave it in the microwave with the door closed, instead of taking it out. In Step 2: Heating time will vary according to the size of the container you use. In my case, I split up my 500 ml of soy milk in thirds to make this tofu.
