A tip for rice...
Don't ever let a Dominican see you cooking rice without cleaning (picking out blackish rice) it very thoroughly and washing it. Also, when preparing rice, don't use too much water (about 1 & 2/3 cup water to 1 cup uncooked rice), and use enough salt. Rice that isn't salty enough just doesn't taste good to them. Finally, when the rice is done cooking, until it is ready to be eaten, put a piece of plastic (a piece of a plastic bag will do) in-between the pot and the lid...they say this keeps the rice from drying out. To tell you the truth, I couldn't tell you if it helps or not.
Cooking rice is an art to Dominicans, I think. My husband doesn't like Chinese food because, quote, "The Chinese don't know how to cook rice". Is that the funniest thing you've ever heard???
