Number 21 on the list of why I love Brazil is.....
Caldo de cana in Portuguese and in English its called Garapa. It is sugar cane juice. Supposedly its energetic which I don't agree with. Here it's very common to get a squeeze of lemon or even pineapple and mix with it. It is obtained from taking the sugar cane and peeling it and then generally people use hand cranked mills to crush the cane, draining the juice from it. It's best served with cold with ice.
Recently my wife introduced me to taking the cane and cutting it into chunks and then sucking the juice out and crushing it with your teeth. I was skeptical at first but then found that I liked it. Gotta keep an open mind.
