1) Add tequila, mango juice, lime juice, and a pinch of chili powder to a cocktail shaker filled with ice.

2) Shake vigorously until the shaker is frosty.

3) Fill a tall glass with fresh ice and strain the mixture into the glass.

4) Slowly pour the grenadine down the inside of the glass so it settles on the bottom for a sunrise effect.

5) Garnish with fresh mango slices and serve immediately.
