I prefer Key limes to Persian limes, but in the Greater Washington area they are often hard to find. Fortunately, this year starting in the spring we've been getting them, so that's all I buy now until they can't be found anymore.

If you squeeze Key limes while they're still green they're definitely going to be very tart. Key limes aren't ripe until they turn yellow. Then, when you cut them open, they are yellow on the outside and on the inside... well...lime green. Yummy.

Here are a couple of links I posted a while back about Persian Limes and Key limes.
