Water ratios and cooking times by rice type
White long-grain (including standard American long-grain): 1 cup rice to 2 cups water, 18 minutes covered on low heat. White short-grain: 1:1.5, 15 minutes. Basmati: 1:1.5, 15 minutes — rinsing removes surface starch and keeps grains separate. Jasmine: 1:1.75, 18 minutes.
Brown rice retains its bran layer and germ, requiring more water (1:2.5) and longer cooking (40 minutes). Wild rice is a semi-aquatic grass, not true rice, needing the most water (1:3) and time (45 minutes). Arborio is listed at 1:3 as a guide, but risotto is cooked by gradually adding hot stock — not the absorption method.
Water (cups) = Dry rice (cups) × Water ratio
E.g. 2 cups of brown rice × 2.5 = 5 cups of water.
Cooked yield (g) ≈ Dry rice (g) × Yield multiplier
Rice roughly doubles to triples in weight when cooked, depending on variety.
