In a medium saucepan, combine apple cider vinegar, granulated sugar, brown sugar, garlic powder, ground ginger, turmeric, and salt. Heat over medium heat, stirring occasionally, bringing to a gentle boil.

Once the syrup reaches a rolling boil, carefully add the drained pineapple chunks. Reduce heat and let simmer for about 15-20 minutes until syrup thickens.

Using a ladle, spoon the hot mixture into sterilized jars, seal while warm, and allow to cool to room temperature before refrigerating.
