The tangy taste of tart key limes explodes with this powerful cheesecake. In order to make this dessert absolutely perfect, we pulled our tart fruits from shrubby trees in the Florida Keys…even thought that's not where they're originally from. Back in the day, these small green treats were native to Southeast Asia but, with the help of travelers and explorers, were introduced to North Africa, the Middle East, the West Indies, and finally to Florida. In FL's sub-tropical climate, they grew so well that everyone decided they ought to share their names. So rest assured: even though our limes don't come from where they originated from, they're picked from where they became famous.
