Muddle the jalapeño: Place one of sliced jalapeño (or both halves if you really like spice!) in cocktail mixer and use muddler to smash it a few times to release oils (don’t overdo it unless you really like heat).

Make a salted spice rim: Place salt, chili powder, and lime zest on a plate and mix until well combined. Wet rim of glass with lime juice and place rim down on salt mixture.
Pour and enjoy: Pour the mixed margaritas into the glasses with salted rims, and enjoy!

Notes
Recipe notes: Use bottled or fresh lime juice. Agave nectar is optional; omit if you like a tart margarita or want a 'skinny' margarita. Orange juice is optional, but provides a smoother taste (especially if you're not using a sweetener). Salted spice rim is optional, but highly recommended.
Prep ahead: Mix margaritas in a pitcher up to two days ahead of serving, but don't add ice to the pitcher until ready to enjoy.
Leftovers and storage: This margarita recipe can be made up to 3-4 days ahead of time, however make sure to strain and remove the jalapeño before storing or else you’ll be in store for a very spicy surprise!
Nutrition notes: Nutrition information is calculated for margarita with agave syrup, but without the salted rim. A margarita is a treat, it is not supposed to be a health food (so my professional recommendation is not to concern yourself with the nutrition in a margarita). However, this homemade margarita is low in added sugar compared to many pre-made mixes.
