1 bag (15 ounces each) purple corn
1 green apple
1/4 pineapple (peeled and cored)
1 pear
2 cinnamon sticks
3 whole cloves
1 cup sugar, or to taste
1/4 cup freshly squeezed key lime juice, or to taste

Add like 3 quarts of water, simmer everything but the sugar and lime for an hour or so. Add sugar and lime juice to taste. I think it's supposed to make 3 quarts but it ends up with more like 2, so you can dilute it more too. The original recipe was 8x this big.
