"Why do you wash rice, and how many times?" is one of the most-asked questions about Japanese cooking on foreign Q&A sites. The Japanese verb is togu — to "polish" or "hone" the rice — but advances in milling have changed what that should mean in practice. Here is the current guide.
| Step | Guide | Why |
|---|---|---|
| First water | Pour off immediately (within 10 seconds) | Dry rice quickly absorbs the smell of bran |
| Washing | Fingertips upright, about 20 light stirs, change the water, 2–3 times | Modern milling makes force unnecessary |
| Cloudiness | Stop when the water is only faintly white | Washing until clear loses nutrients and flavour |
| Soaking | About 30 minutes in summer, 1 hour in winter | Lets water reach the core of the grain |
| Water | 1.2 times the rice (by weight); in a rice cooker, use the marked line | Slightly less for new-crop rice (shinmai) |
| After cooking | Rest 10–15 minutes, then turn it over from the bottom | Evens out the moisture |
[Verify] Check the consumption figure against the latest fiscal year of MAFF's "Food Balance Sheet". Washing guidelines vary with milling technology and the type of rice.
Washing until clear rinses away the surface starch and flavour, and the grains break more easily. The current guide is to stop when the water is faintly white.
Musenmai is rice whose bran has been removed industrially, and it needs no washing. Use a little more water than usual. Any difference in taste is generally described as a matter of preference.
Rice is best stored cool and dry. In an airtight container in the vegetable drawer of the fridge, it is protected from summer insects and from oxidation. Aim to use it within about a month of opening.
Rice that has sat a long time since milling loses flavour, but is edible if there are no insects or mould. Soaking it longer, or adding a little sake or a few ice cubes when cooking, are tricks shared among Japanese households.
Keep-warm is for a few hours; longer causes yellowing and off-smells. Portion the rice and freeze it as soon as it is cooked — the standard approach for both taste and hygiene.
