4 ounceslight agave syrup, plus more for rimming the glasses
1 medium avocado, peeled and pitted
Mix together the thyme and salt in a small, shallow bowl. Place a small amount of agave syrup in another small bowl. Using your finger, rim 6 shooter glasses with the syrup, then dip the rims into the thyme-salt mixture. Set the glasses aside.
Place the remaining ingredients except the ice in a blender and blend on high until smooth.
Fill a cocktail shaker halfway with ice. Pour in some of the blended mixture, filling the shaker about halfway. Shake until thoroughly chilled, about 20 to 30 seconds. Strain into the rimmed shooter glasses. Repeat with the remaining blended ingredients. Serve immediately.
