Add all the ingredients in a medium-size metal bowl and stir.
Pour the liquid into a large freezer bag, and place it in the freezer until frozen for approximately 4 hours.
When ready to drink, massage the freezer bag by hand until it’s a wet, slushy consistency. If it’s not breaking up, run the bag quickly under hot water and massage some more.
Divide among four Old Fashioned or rocks glasses.
Garnish each glass with a strip of crispy bacon.
