In a cocktail shaker with ice, combine tequila, orange liqueur, agave, lime juice and blood orange juice.
Shake for 10-15 seconds until well chilled.
Pour into your prepared cocktail glass with fresh ice. Garnish with a slice of blood orange.
Notes
It is normal for some blood oranges to be very different colors inside, ranging from deep red to orange.
If you don't want to do a Tajin rim, try using kosher salt.
This is a great cocktail to batch into a pitcher recipe. Multiply this recipe by eight and serve it in a large pitcher with orange slices floating on top.
