Add some spice to your life and your Margarita with fresh Jalapeño slices. I’ve used bottled Jalapeño slices and juice to perk up Margaritas but I found the fresh slices had more flavor with less burn. There are lots of variants on the Internet including those with chili pepper and pepper jelly. Stick with 100% agave tequila, fresh lime juice, a little orange liqueur and we’re good to go.
