rice that learned discipline, browning each grain before it dares touch water
means A dish of rice cooked in seasoned broth, often with the grains first toasted in fat, sometimes folded together with meat, vegetables, or spices.
from From Turkish 'pilav,' itself from Persian 'pilāw' — the word traveled the same routes the dish did, spreading from Persia across Central Asia, the Middle East, India, and the Balkans, picking up local spellings along the way (pilau, pulao, pilav, plov). English borrowed it, as English does, from whoever was serving it at the time.
