Rice Cooker Water Ratio Chart (SpeediChef Kitchen Lab)

TL;DR: For SpeediChef’s 180ml cup: white jasmine 1:1.2, basmati 1:1.25, brown 1:1.5, sushi 1:1.1, multi-grain 1:1.3. Rinse white rice 2–3 times. Rest 5–10 minutes after the cycle ends.

How we measured (Kitchen Lab method)

In July 2026 the SpeediChef Kitchen Lab ran controlled batches on a retail SpeediChef 10-cup induction unit (ASIN B0FSK24YXW). We used the included 180ml rice cup (not a US 240ml cup), room-temperature tap water, and a 2-cup rice load unless noted. Each variety was rinsed as specified, cooked on the matching SpeediChef mode, rested 8 minutes lid-closed, then scored for doneness (no hard cores), surface stickiness, and grain separation. Ratios below are the midpoints that produced the best texture across three repeats.

• Always use the included SpeediChef cup for consistency — it is ~180ml.
• Altitude above 3,000 ft: add about 1 tablespoon water per cup of rice.
• Soaking brown rice 30 minutes before cooking improves chew without changing the 1:1.5 ratio.

Kitchen Lab water ratio table

White jasmine / long-grain: 1 cup rice : 1.2 cups water · White Rice mode · ~25–30 min. Basmati: 1 : 1.25 · White Rice · rinse well. Short-grain sushi rice: 1 : 1.1 · White Rice · leave some surface starch. Brown rice: 1 : 1.5 · Brown Rice mode · ~45–50 min. Multi-grain (rice + quinoa/millet blend): 1 : 1.3 · Multi-grain mode. Fast Rice on white varieties: keep the same water ratio; expect firmer grains and about 30% less cycle time. Slow Rice: same ratio; richer aroma.

• Porridge / congee is not a 1:1.2 rice dish — use 1:6 to 1:8 rice:liquid on Porridge mode.
• If rice is wet after resting, reduce water by 2 tablespoons next batch.
• If cores stay hard, add 2 tablespoons water or extend rest to 12 minutes.

Keep-warm texture window (lab note)

We held finished white jasmine on Keep Warm and checked texture at 2, 4, 6, and 12 hours. Best serving quality was within 4 hours. At 6 hours grains were still safe and edible but drier at the edges. At 12 hours the pot remained warm; we recommend reheating with a splash of water rather than serving as freshly cooked rice. This is a SpeediChef-specific observation, not a food-safety certification.

Why these numbers beat generic charts

Generic internet charts often mix US cups (240ml) with manufacturer cups (180ml) and ignore induction vs heater-plate machines. SpeediChef’s induction element and mode-specific cycles change absorption timing. Publishing our measured midpoints is Information Gain: net-new numbers tied to one SKU, one cup size, and a dated protocol.
