I have been making a three pepper chili for years, but the spice content leaves a little to be desired for some people. I wanted to make a hot sauce that would complement this chili, but my first few attempts haven't been hot enough. I used jalapeño and poblano as the base along with vinegar and garlic. The sauce tastes exactly how I would like and tastes great with the chili, but it isn't hot enough. So, is there any way to torque up the heat with out changing the taste?
(I did use a few habanero on one batch but all I can taste is the addition, it throws the sauces flavor off in a fairly noticeable way)
