Other precautions about rice when making sushi:
1, it is best to cook with a rice cooker. Wash the rice before cooking. Do not rub it with your hands, but use a rice spoon or a wooden stick to stir it until the water is clear. How much should I put in the water? Just put your whole palm in the rice pot and let the water reach your wrist.
2. Cooked rice should be mixed with vinegar. If you can afford it, you'd better buy kelp vinegar. If you can't afford it, you can use white rice vinegar instead. But no matter what vinegar, you should burn it beforehand, add some Japanese sake (if not, you can replace it with white wine) and add some sugar. The specific amount depends on personal taste. The main principle is that it is better not to have the sour taste in the original vinegar.
3, vinegar and rice mix well, rice should be hot, bibimbap should be big, not too deep, it must be big, so that it will be breathable and the rice will not stick together. The vinegar should be added little by little, and mixed while adding it. It is best to have a large wooden basin if possible, so that the rice will not be cold quickly. How much vinegar should I add? Add it until the rice is sour, and the taste can be heavier, because when the rice is cold, the taste will fade.
