How to Use a Rice Cooker

Measure with the cup that came with it

The first thing to know is that a rice-cooker “cup” is not a US cup — it is a 180 ml rice cup, and every ratio the manufacturer prints assumes it. Use the plastic cup that came in the box, and fill the pot's water line to the mark for the number of rice cups you added. If you lost the cup, measure rice and water in the same vessel and keep theratio right; the absolute size matters less than getting both from the same measure.

Water-to-rice ratios by type

As a starting point, by rice cups to water: white long-grain about 1 : 1.25, white medium/short-grain about 1 : 1.2, brown rice about 1 : 1.5 to 1 : 2 with a longer cook, and jasmine or basmati a touch less water, around 1 : 1.15, because you want the grains separate. A fuzzy-logic or induction cooker with dedicated menus adjusts a lot of this for you — one of the reasons a premium cooker is more forgiving — but the ratios above are a reliable baseline for any machine.

To rinse or not to rinse

For white, jasmine and sushi rice, rinse until the water runs mostly clear— it removes surface starch and gives you separate, less-gluey grains, and it is the single biggest upgrade to homemade rice. Rinse in the mesh, not the nonstick pot, to avoid scratching the coating. The exception is enriched or “rinse-free” rice, where rinsing washes off added nutrients — those cookers often have a dedicated rinse-free setting for exactly this.

The rest almost everyone skips

When the cooker clicks to Warm, leave the lid on for 10–15 minutes before you open it. The rest lets the moisture redistribute so the grains firm up evenly instead of being wet on top and dense at the bottom. Then fluff with a paddle, lifting rather than stirring, to separate the grains without crushing them. Skipping the rest is the most common reason home-cooked rice is gummy even from a good cooker.
