Instructions
Step 1
Thinly slice the cucumber, toss with salt, and let sit for 10 minutes. Squeeze out any excess moisture.
Step 2
Cook the rice with slightly less water than usual. Once the rice is cooked, quickly mix in the sushi vinegar, then fan the rice to cool slightly. Add [C] and mix well.
Step 3
Cut each fried tofu pouch in half. Boil in water for 5 minutes, then drain and gently squeeze out the excess liquid using a wooden spatula.
Step 4
Add [A] to a saucepan and bring to a boil. Reduce to medium heat and simmer for 2–3 minutes. Add [B] and the tofu pouches from step 3, then simmer for 5 minutes. Remove from the heat and let the tofu absorb the flavor.
Step 5
Lightly drain the tofu pouches and fill them with the rice mixture from step 2, divided into 20 portions.
