Prep the peppers. If using larger peppers, start by slicing the peppers in half and removing the seeds (optional). Next, chop the peppers into pieces small enough to fit into the jar you plan to bottle the pique in.
Combine. Add the peppers, garlic, oregano, peppercorns, salt and vinegar to your jar. Make sure to leave an inch or two of space at the top of the bottle. Seal and shake the bottle to get everything mixed together.
Store. Let the pique sit on your countertop for a few days before using on whatever you like.
