Pour a thin layer of Tajín on a small plate, line the rim of a rocks glass with lime juice, and dip the rim of the glass into the tajin to coat the rim.

Add ice, tequila, Grand Marnier, lemon, and two heaping spoonfuls of Mango Pineapple Habanero Chili Jam to a shaker. Shake well to break down the jam.

Fill a rocks glass with ice and pour the shaker contents into the glass.

Garnish the glass with a lime slice and Cheers!
