Begin by washing the hot peppers and patting them dry.
Decide on the level of heat you prefer for your vinegar. For milder vinegar, make a small slit in each pepper. If you desire a more fiery vinegar, slice each pepper in half, keeping the seeds and membrane intact.
Use gloves for safety, and prepare the peppers per your chosen heat level.
Once done, place the prepped peppers into a clean and sterilized glass jar or bottle.
In a saucepan, gently heat the vinegar. Make sure it gets warm, but avoid bringing it to a boil.
Now, with great care, pour the warmed vinegar over the peppers in the bottle or jar, making sure they are fully submerged.
Allow this mixture to cool down completely before securing the bottle or jar lid.
For the ultimate flavor experience, let the vinegar steep for at least a week before using it. The longer it infuses, the more robust the flavors will be!
