All ingredients ready? Let's begin!
In a small mixing bowl, whisk together the chili powder, salt, lime powder, and 1 teaspoon of sugar.
Spoon this mixture onto a flat plate and spread it out evenly.
On another plate, add 2 tablespoons of chamoy sauce and spread it out with the back of a spoon. Set both plates aside.
To a blender, add the frozen mango, mango nectar, lime juice, 1 tablespoon of sugar, and the ice. Blend until smooth and creamy, approximately 1 minute.
Take your cups and dip the rims in the chamoy on the plate and then in the chili lime seasoning. This is similar to the salt rim on a margarita glass.
Spoon 1 tablespoon of chamoy into each glass and swirl to coat the bottoms.
Pour some of the mango purée into each cup to fill halfway. Add another tablespoon of the chamoy to each glass. Fill the glasses with the remaining mango purée.
Top each glass with fresh mango chunks. Sprinkle any leftover chili lime spice over the mango chunks. Add a tamarind candy straw and serve immediately while cold.
