In a large pot over high heat, combine the chiles, vinegar, and salt. Bring to a boil, then reduce the heat to medium and let simmer for 5 minutes, or until the chiles are soft.
Transfer the chile mixture to a blender or food processor, then blend until smooth, leaving a vent to allow steam to escape. Let it cool to room temperature.
Transfer the sauce to an airtight container and refrigerate for 2 weeks before using.
Store in the refrigerator for up to 4 months.
Notes
The flavors deepen and grow more complex during the 2-week refrigeration time, but if you're itching to enjoy this hot sauce right away, you can indeed do so!For an even more traditional Louisiana hot sauce, replace the jalapeno with cayenne peppers instead. This recipe really works great with just about any red chile!This recipe can also be found in my book Hot Sauce Cookbook for Beginners.
