Then add the apple syrup, sweet and sour mix, and the grenadine.
Stir gently with a cocktail spoon to help the colors mix (but only a little bit so you still get that black / green ombre hue) and serve!
Notes
The nutrition information is off as the program doesn't have facts for the green apple syrup or the sweet and sour mix. You can make the up to three days ahead of time and store it in the fridge ready to serve to guests. Don't love tequila? Try it with vodka or gin. Cut some of the sweetness by making your own homemade sweet and sour mix with fresh citrus.
