We live in a city that regularly sees temperatures above 90 degrees. Fortunately, Miami's climate is also ripe for growing awesome produce of all kinds. That means there is no reason to settle for a made-from-concentrate, prepackaged juice box when you can have the real thing. Futuro Supermarket is like a blast from the past with its antiquated cash register and small aisles. But way at the back of the store sits the perfect oasis. Mango, pineapple, orange, carrot — the list of fresh juices goes on and on. They're served in a 16-ounce Styrofoam cup ($2) or sold by the half-gallon ($6). Either way, they taste like you just bit into the fruit itself.
