In a shaker, muddle raspberries and mint until fruit releases its juice.
Fill ¾ of the way with ice and pour in mezcal, simple syrup and citrus juices.
Shake well for at least 30 seconds
Use the leftover citrus peel to rim around your glass and dip rim in tajin.
Fill glass with ice (crushed works too) and pour drink without straining.
Garnish with fresh raspberries and mint sprig.
Notes
This drink is highly customizable with other berries or citrus, so have fun with it!
If you like a smoother drink textually, strain the cocktail instead, but I love the bits of fruit and mint.
