Rice Water Ratio & Cooking Time Calculator

Perfect Rice Cooking Guide

What's the key thing to understand about Rice-to-Water Ratios?

The correct water ratio varies significantly by rice type. Long-grain white: 1:1.5-1.75 (rice:water by volume) or 1:1.8 by weight. Basmati: 1:1.5 (rinse first — removes excess starch). Jasmine: 1:1.4 (slightly less water — jasmine is more moist). Brown rice: 1:2.0-2.5 (longer cooking, more water). Sushi rice: 1:1.1-1.2 (less water — the vinegar seasoning adds moisture). Wild rice: 1:3 (significantly more water, very long cooking time). Arborio/risotto: not applicable — water or stock is added gradually during cooking rather than measured upfront, since the technique relies on continuous stirring and incremental liquid addition.

What do I need to know about The Absorption Method?

Rinse rice until water runs clear (especially basmati and sushi rice — reduces stickiness and removes excess starch). Add measured water plus a pinch of salt. Bring to a full boil with the lid on. Immediately reduce to the lowest possible heat. Cook for the required time without lifting the lid — the steam is doing the work. Remove from heat and leave covered for 5-10 minutes (resting allows the rice to finish absorbing steam evenly). Fluff with a fork, never a spoon (which compresses the grains and can make the rice gluey rather than light and separate.

Why Rice Cookers Work Better?

Rice cookers achieve consistent results because they detect when all the water has been absorbed (the temperature rises above 100°C once no water remains to evaporate) and automatically switch to 'warm' mode. This eliminates the timing guesswork and the lid-lifting temptation. Fuzzy logic rice cookers adjust cooking based on detected rice type and quantity. For daily rice consumption, a basic rice cooker (£20-50) produces results that are difficult to replicate consistently on the hob. Japanese rice cooker brands in particular are known for producing consistently excellent results, since their fuzzy-logic sensors adjust cooking time and temperature automatically based on the rice and water detected.

What should I know about Storing and Reheating Cooked Rice?

Food safety: rice contains Bacillus cereus spores that survive cooking and can multiply rapidly at room temperature. Cool cooked rice quickly (within one hour, spread on a wide dish), refrigerate in an airtight container, and use within 24 hours. Never leave cooked rice at room temperature for more than 2 hours. Reheating: rice must be piping hot all the way through (minimum 75°C). Add a splash of water before microwaving and cover to create steam. Never reheat rice more than once. Fried rice is actually one of the best uses for day-old refrigerated rice, since slightly dried-out grains fry better and stick together less than freshly cooked rice.
