I have the 3 cup capacity and it is perfect for 1 or 2 people. It's small and cute and can sit on the counter if you have space, or easily stored (retractable cord hides underneath.) There are bigger models for larger families.
I use it for sushi rice, basmati rice, wild rice, Rice & Beans, Mexican rice, brown rice, porridge, oatmeal, polenta, wheat berries; basically anything that absorbs its cooking liquid.
The real perk is that the perfectly cooked rice stays perfect LONG (hours and hours) after cooking. I can turn it on when I get home and it's ready whenever I get around to putting together whatever is going with the rice. There is also a timer; if you're really organized you could set it in the morning for dinnertime.
I forgot to even mention that the cooking bowl comes out and is so easy to clean. Thanks for the comment Binx.
1 cup long grain (brown) rice (plus water according to package)
1 Tbs annatto oil (annatto seeds steeped in oil-I use corn oil)
1/4 cup pitted alcaparrado (fancy name for olives with pimentos and capers)
1/2 cup sofrito (onion, garlic, peppers, cilantro)
Throw all that in the rice cooker with the water amount for the type of rice you're using and press the shiny red button (in the voice of stimpy) or:
Cook rice with the amount of water and cooking time on package, adding oil, olives and capers (and a little extra brine if you like) and sofrito.
