In a small sauce pan add vinegar, salt, sugar, mustard seeds, pepper corns, garlic, and chilis. Bring to a boil over medium heat.
Turn off the heat and allow boil to stop. Add the hot vinegar and pickles to a glass container. Add enough fresh cool water to cover the pickles, about 3/4 cup, and stir to combine.
Loosely cover container so steam can escape. Transfer to the refrigerator and allow to cool.
Ready to eat in about an hour. Wait 24 to 48 hours for better results.
