In a 2-quart nonreactive saucepan, combine the marinade ingredients (Water, apple cider vinegar, kosher salt, garlic, sugar, yellow mustard seeds, hot sauce, celery seeds, bay leaf and whole black peppercorns) and bring to a boil over high heat.
For 3 to 4 minutes, turn down the heat and keep a simmer.
After taking it off the heat, stir in the ice for getting cold.
Place the cooled pickling liquid and the pork in a 1-gallon zip-top bag.
Seal the bag after removing as much air as you can.
Put it in the fridge for at least 3 to 4 days, occasionally flipping the bag.
Use within fourteen days, or take the pork out of the brine and freeze it.
