After this time, do not hesitate to catch a piece of meat and bite it off. As a rule, it is already ready. Cover the rice and turn down the heat again to maximum. Intervene while nothing is needed. We need to wait for the water to boil off the surface, it was not enough for long. You can “pierce” the mass of rice to the bottom in several places (with the back of the skimmer, for example) so that the liquid boils not only at the edges, but also in the middle of the dish.
When the water disappears from sight, boils off, turn off the stove, cover the cauldron with a lid, you can just put the plate in the cauldron, but then, as for me, it is very inconvenient to take it out. I suggest covering the pan and the whole thing with a towel.
