Give the pineapple a thorough wash if keeping the skin on, or peel and wash it before chopping into 1 cm pieces. More is explained in the video below, especially if you're keeping the skin on vs peeling.
Place the dried sorrel into a deep soup or stock pot.
Add the cinnamon stick, bay leaves, dried orange peel, ginger, and cloves with the stove turned off.
Add the chopped pineapple, followed by the water, then bring the pot to a boil over medium-high heat.
Reduce the heat to a simmer and cook for 30–40 minutes.
Turn off the stove and allow the mixture to steep for at least 4 hours. Overnight steeping gives the best flavor.
Strain the mixture, squeezing well to extract all the liquid from the rehydrated sorrel and pineapple. As mentioned in the video below, the pineapple and sorrel remnants can be used to make a jam, jelly, or chutney. Please comment below if you'd like to see the recipe.
Sweeten to taste, bottle, and store in the refrigerator for up to 6 weeks.
Serve chilled over ice and garnish with fresh pineapple or lemon slices if desired.
