California rolls with avocado, shrimp and red caviar

Did you know that classic California rolls can be made at home? And by your own example, make sure that this food of Japanese cuisine is not coincidentally considered the food of kings. I found this recipe on a good website on the Internet. To be honest, it wasn't me who cooked it, but my friend – I was only present nearby and, of course, took the first sample. Needless to say, the rolls turned out to be simply delicious.
Carefully washed rice is lowered into a saucepan, pour a glass of water and cook for ten minutes, first on medium, then on low heat. We do it under the lid. After giving the rice to infuse for another ten minutes. Pour vinegar into a saucepan, a spoonful of boiled water, salt and sugar and heat over the fire. Then we pour the rice with the resulting liquid and stir it sharply with one hand, with the other scattering the vinegar vapors coming out with a fan. Cover again with a lid and set aside until completely cooled. Peel the avocado and cut it into oblong slices. We divide each shrimp in half. We take mayonnaise and fill it with wasabi and soy sauce, bring it to a homogeneous state. Next to it we put a saucepan with water diluted with a tablespoon of vinegar.
Nori is laid on the mat with the glossy side to the table. We moisten our hands in vinegar water, take rice and spread it evenly on the nori. Turn over to the other side and fill with our filling: avocado, shrimp and sauce – one half of nori. Now, with the help of a mat, we give our rolls a quadrangular shape, take them out and roll them in red trout caviar. Then cut into portions.
