After my snack of chontaduro, the same vendor leaned down and took out a red and white thermos cooler from beneath her cart. She screwed off the lid and inside I saw a creamy soup that I presumed to be a fruit and milk blend. She ladled out a cup for me to try. It tasted like a milkshake of plums and vanilla and something earthy, sweet. It tasted thick and tropical. When I asked for the recipe I expected milk, sugar and vanilla to be listed. No, I was told. The sole ingredient was the Borojo fruit itself.

After two cup fulls, then came the warning. The drink is famous for being an aphrodisiac.
