Set out two shallow dishes and two glass tumblers or hurricane glasses. In one dish pour 1 tablespoon of Chamoy sauce. In the other dish pour 1 tablespoon of Tajin seasoning. Dip the rims of the glasses first in Chamoy sauce, followed by the Tajin seasoning. Set the glasses aside.
In the blender, combine frozen mango chunks, pineapple juice, and fresh lime juice. Purée until smooth and thick. If needed, add another splash of juice to loosen up the mixture.
Once the smoothies are ready, drizzle Chamoy sauce inside the glass, all around the edges, about one tablespoon per glass.
Then pour or scoop the mango slushy into the prepared glass. The chamoy sauce will separate and make designs on the sides of the glass.
Serve as-is, or garnish with a Tamarindo candy straw, a lime wedge, and chunks of fresh-cut mango.
Notes
Booze it up, by adding 4 ounces of rum or tequila to the blender, 2 ounces per beverage.Additional variations: You can also mix things up with your mangonada by using all sorts of unique tropical fruit nectars or juices such as pineapple-guava-banana.
