Remove the stems from the jalapeños and slice them into 1/4-inch thick coins.
Keep the seeds for extra heat if you like things spicy!
Combine the apple cider vinegar, granulated sugar, garlic powder, ground turmeric, and celery seed in a medium saucepan.
Bring the mixture to a boil over medium heat.
Once the mixture is boiling, reduce heat and simmer for about 5 minutes.
Stir occasionally to dissolve the sugar fully.
Add the sliced jalapeños to the pot.
Simmer them for 4 minutes, ensuring they are all coated with the syrup.
Transfer the jalapeños to sterilized jars using tongs.
Then pour the remaining syrup over the jalapeños, making sure they are fully covered.
