A fruity, fizzy, and slightly boozy frozen margarita float combining frozen strawberries and blueberries with tequila, lime, and sparkling soda for a perfect summer refresher.
Use frozen berries for best texture; if using fresh berries, freeze for 30 minutes before blending. Do not overblend to avoid watery texture. Add soda last and pour slowly to keep bubbles. The berry base can be made ahead and stored in the freezer up to 24 hours. For a non-alcoholic version, omit tequila and add extra sparkling water or lemon-lime soda. Optional salt rim enhances flavor.
