Rim the glasses. If you don't have a glass rimmer, you can use two small plates. First dip the glass upside down into lime juice or wipe a lime wedge all the way around. Then dip the glass and swirl it around on a plate with margarita salt.
In a blender, add the blueberries and lime juice. Pulse lightly until you have a slightly broken up mixture. Add the rest of the ingredients including ice and pulse until mostly smooth. If using straws for your drinks, you may need to add a bit of water to make it the right consistency.
Pour the blueberry puree into glasses. Garnish with a lime wheel and blueberry skewer. Enjoy!
Notes
How To Make a Blueberry Margarita for One: 2oz Tequila (4 Tbsp), 0.5oz Triple Sec (1 Tbsp), 1tsp lime juice or 1 squeeze of a lime, ⅓ cup of blueberries and 1 cup of ice. it isn't particularly easy to blend a single cocktail unless you have a small mixer like a ninja.How To Measure Alcohol: When I worked as a bartender, we used a jigger or a 4-count free pour technique (4 count = 1 oz) with a pour spout. At home, if you don't have a jigger, 1oz equals 2 Tbsp.
