Step 1

Add salt to a small plate. Use a lime wedge to wet the rim of the glass; dip the top of the glass in the salt, rolling from side to side until well coated.

Step 2

Next fill a cocktail shaker with ice. Add the tequila, lime juice, watermelon juice, jalapeno slices, and agave nectar. Put on the lid and shake for 15-30 seconds; strain the liquid into a glass and garnish with a fresh watermelon wedge. (You can also add a few jalapeno slices to the bottom of the glass, but only if you like it extra spicy!) Taste and add extra sweetener if necessary.
