Adventures with Kake

米 (mǐ) is the Chinese character for uncooked rice and other grain-like things.

Note that the character for cooked rice is 飯 (fàn), though this is often used on menus in combination with 米 as 米飯 (mǐ fàn). I've seen 米飯 used to denote plain steamed rice, though in comments below sunflower points out that really this is just another term for cooked rice, and sung reminds me that 白飯 (bái fàn) is the more commonly-used term for plain cooked rice in Cantonese (白 means white/pure/plain).

Other words that include 米 are:

小米	xiǎo mǐ	millet (literally "small grain")
米粉	mǐ fěn	rice vermicelli
玉米	yù mǐ	sweetcorn
粟米	sù mǐ	another word for sweetcorn
蝦米	xiā mǐ	dried prawns
海米	hǎi mǐ	another word for dried prawns
花生米	huā shēng mǐ	peanuts — also simply 花生; note that pulchritude mentions in comments that 花生米 is specifically the kernels rather than the whole nut, and also that 花生米 also refers to "an appetizer-ish dish containing salted peanut kernels (with the red skin left on)"

And here are some dishes with 米 in the name:

Note in the last of these that the 米 is attached to the preceding 蝦 to make 蝦米 (dried prawns) rather than to the following 粉 to make 米粉 (rice vermicelli). The 粉 in turn is attached to the following 絲 to make 粉絲 (bean thread noodles). I discussed the issue of working out which word a character belongs to in my post on 鹹蛋黄玉米粒 (xián dàn huáng yù mǐ fěn (sweetcorn with salted egg yolk) — essentially, there's no substitute for experience.
