Japanese cuisines are one of the top cuisines. I am in learning process in cooking and I try to attempt some jap dishes too. The basic inari sushi recipe is one of them and to make it I used fried tofu pockets, short grain rice, 2 cups of water, white vinegar, sugar, some salt, soy sauce, mirin, dashi the fish stock, sesame seeds, saucepan with lid, rice cooker and a large pot of mixing bowl. I mix the rice with vinegar, sugar then add then cook the rice in the rice cooker. Then I let the rice to cool to just above the room temperature. And then followed the rest of the regular process to make the basic inari sushi recipe. Why did my sushi crumbled down when tried to pick up? I am feeling so bad about the whole thing. How can I fix it? Kindly help.
