Prepare your ingredients by dicing the fresh pineapple into bite-sized chunks and slicing the jalapeños thinly, removing the seeds and membranes for a milder flavor.

Combine the diced pineapple, sliced jalapeños, granulated sugar, apple cider vinegar, ginger, and lemon juice in a large pot. Stir gently and bring to a gentle boil, allowing the flavors to meld together for about 5-7 minutes.

Reduce the heat to medium-low and let the mixture simmer, stirring occasionally, for around 20-30 minutes until it thickens and becomes sticky.

While simmering, sterilize your jars and lids by boiling them in water for 10 minutes.

Pour the hot candy into the sterilized jars, leaving a quarter-inch of space at the top and seal tightly with lids.

Allow the jars to cool undisturbed for 12-24 hours at room temperature, storing them in a cool, dark place.
