If you don’t want to put crushed peppermint candies as a garnish in the center of the smoothie, you can also rim your glass in crushed peppermint. As if you were making a cocktail, put a little water or honey on a plate and lightly dip the rim of your glass in the liquid. On a separate plate, place the crushed candy and then dip the rim of your glass to create a candy-coated lip to your drink.
