Slice your smoked sausage into bite-sized pieces.
Pack them tightly into a large glass jar.
Add sliced jalapeños evenly throughout the jar.
In a saucepan, combine white vinegar, water, and sugar.
Stir well over medium heat until sugar completely dissolves.
Add crushed red pepper, black peppercorns, and pickling spice to the mixture.
Toss in the garlic cloves for extra flavor.
Stir occasionally until the mixture begins to boil.
Once boiling, carefully pour the hot liquid over the sausages and jalapeños in the jar.
Make sure everything gets evenly submerged in the brine.
Seal the jar tightly once full.
Let the jar cool to room temperature.
Refrigerate for at least three days to allow the flavors to meld.
Serve and enjoy your pickled sausages!
