How to Make It
Spread the chile powder in a dish. Moisten the rim of a margarita glass with the lime wedge; dip the rim in the chile powder to coat. In a blender, puree the mango. Add the remaining ingredients and blend until smooth. Pour into the glass and serve.
Tajin chile powder gets its tang from dehydrated lemon juice. It is available at Latin markets and online at mifiesta.com.
