Which step is NOT part of the preparation for the Strawberry Watermelon Margarita?

The preparation for the Strawberry Watermelon Margarita involves several specific steps to ensure the drink is made correctly and tastes delicious. Adding soda water is not a typical step in the standard preparation of this cocktail. Instead, the focus is on the fresh flavors of the strawberries and watermelon, complemented by lime and potentially other ingredients, without the need for carbonation from soda water.

Rimming the glass with green sugar enhances the visual appeal of the drink and adds an additional flavor element. Shaking and straining the ingredients is crucial for mixing the flavors thoroughly and achieving the desired consistency. Dropping a lime over strawberry ice can enhance the citrusy brightness, making it more refreshing. Each of these steps contributes to creating a well-balanced and flavorful cocktail, while the addition of soda water would not be necessary or traditional for this drink.
