- Combine purple corn, pineapple scraps, apples, cloves, cinnamon, and water in a large stockpot. Bring to a boil, cover the pot, and reduce to a simmer, covered, for 45 minutes and then uncover the pot and continue simmering for 30 more minutes until the corn kernels should have cracked open.
- Strain the liquid into an open container and let cool.
- Stir in lime and lemon juice. Sweeten to taste. Put in the fridge until completely chilled and serve over ice. Garnish with lime or chopped apple and pineapple, if desired.
