Mix Tajin seasoning on a small plate. Run a lime wedge around the rim of the glass and dip in the seasoning.
Add tequila, lime juice, mango puree, cream of coconut, and triple sec to a shaker filled with ice.
Shake vigorously for 15-20 seconds until well chilled.
Strain into the prepared glass filled with fresh ice.
Garnish with a fresh mango slice and lime wheel.
Notes
Store cream of coconut in the fridge after opening. It will stay fresh for up to 2 weeks.Make fresh mango puree by blending ripe mango chunks until smooth. Strain if needed.For a frozen version, combine all ingredients with 1 cup of ice in a blender until smooth.Skip the Tajin for a simpler drink. Regular salt or coconut flakes work well too.
