Rice to Water (White Varieties)

1 part by volume

Long-grain white rice (e.g. Thai jasmine, American long-grain) — Unrinsed; rinsing reduces ratio to ~1:1.4

1.5 parts by volume

Water or light stock — Bring to boil, reduce to lowest simmer, cover tightly

¼ tsp per cup of dry rice

Salt — Optional but improves flavour and gel clarity

Combine rice and cold water in a heavy-bottomed saucepan with a tight-fitting lid. Bring to a full boil over high heat, stir once, reduce heat to the absolute minimum, cover, and cook undisturbed for 15–18 minutes (long-grain) or 12–13 minutes (short-grain). Remove from heat and let steam, covered, for 10 minutes before fluffing. Never lift the lid during cooking — steam is part of the ratio.

• Rinsing removes talc coating (on some imported rices) and excess surface starch; always rinse until water runs clear for fluffy separate grains.
• Soaking short-grain or basmati for 20–30 minutes before cooking gives more even hydration and reduces cooking time, letting you lower the water ratio.
• Altitude matters: water boils at lower temperatures above 1,500 m, so grains cook more slowly; increase water by 2–3 tbsp per cup and extend cooking time.
• The 'finger method' (water level sits 1 knuckle above the rice surface regardless of volume) works because the absorption geometry scales with pan diameter, not absolute volume.
• Old-crop rice (stored over one season) is drier than new-crop; it absorbs more water and benefits from longer soaking.
• Do not salt the water when cooking rice for sushi — it impedes vinegar seasoning absorption.

• Japanese short-grain / sushi rice (1:1)

  High amylopectin content; grains cling; less water than long-grain; soak 30 min before cooking for best texture

• Basmati (1:1.5, soaked)

  Soak 20–30 min, drain, then use 1:1.25–1.5 depending on age of rice; older basmati is drier and needs more water

• Parboiled / converted rice (1:1.5–1.75)

  Parboiling gelatinises the starch before milling; grains cook firm and separate; needs slightly more water and longer cooking

• Rinsed long-grain (1:1.4)

  Rinsing removes surface starch; reduces stickiness; shave ~10% off water to avoid mushiness

• Rice cooker short-grain (1:1 or fill line)

  Rice cookers are calibrated for specific cups (often 180 ml, not 240 ml); use the cooker's own cup and fill line for most reliable result

• Pilaf method (1:1.75, with fat)

  Toast rice in butter or oil before adding hot liquid; fat coating slows initial absorption; ratio increases slightly

• Congee / Jook Water-to-Rice Ratio

  8:1–12:1; the extreme end of the absorption spectrum, producing a thick rice porridge

• Risotto Liquid Absorption Ratio

  ~4:1 stock to arborio/carnaroli; ladled progressively rather than absorbed in a single charge

• Pilaf Ratio

  ~1:1.75 with toasted rice; fat coating and oven finishing alter absorption dynamics
