Frequently asked questions
Why does brown rice take longer than white?
The fibrous bran layer blocks water from reaching the starch inside. 25 minutes simmering versus 12 for white rice.
How much water does brown rice need?
About 1 part rice to 2.5 parts water — more than white rice because the bran absorbs extra.
