Stir the okara and salt well in a bowl. Add the katakuriko and mix some more. Add water. The gnocchi batter will become too crumbly if you mix with a spoon or similar after adding water, so squeeze and knead it with your hands instead.
Roll into bite-sized balls as if you're making dumplings. Shape them with your fingers and press down to flatten slightly.
Cook for about 3 minutes in boiling water until the gnocchi float to the top. Done!
Heat some tomato sauce in a frying pan. Mix it up with the gnocchi to serve.
An alternative would be stir-frying the gnocchi to season with salt and pepper, or to serve with grainy mustard and yuzu pepper.
Story Behind this Recipe
Recently, I've been thinking a lot about healthy food.
By the way, here's how to make my Easy Tomato Sauce! Spread some oil in a frying pan. Add 1/2 clove of garlic and sauté until fragrant. Add 1/4 minced onion. Sprinkle lightly with salt, and sauté well. Add 1/2 can of canned tomatoes and 1 tablespoon sake. Simmer for 10 minutes while mashing the tomatoes with a spatula. Taste, and season with salt, pepper, and herbs like basil if available. Mix, and remove from heat.
