Use disposable gloves while thinly slicing your jalapenos to protect yourself from the burning oils naturally found in the peppers.
Transfer sliced jalapeños into a 14 oz jar. Add in your garlic.
In a small saucepan add in the remaining ingredients and place over medium heat. Bring to a simmer, and whisk to combine.
Once the brine is simmering and everything is incorporated well, remove from heat and pour over the jalapeños.
Allow it to cool to room temp, uncovered.
Cover and refrigerate for up to 2 weeks.
Your pickled jalapeños are ready to eat in 24 hours.
Enjoy!
