It's really easy, it just takes a bit of planning because you have to infuse the tequila with sliced jalapeños which takes some time. The range of time varies widely. Some recipes call for 15 minutes while other's call for 24 hours. I infused it for 1 1/2 hours and it had a nice kick to it. Infuse it longer if you'd like it spicier and shorter if you want to keep things more mild.
