Step 1: Prepare your ingredients. Ensure your strawberries are frozen. This will provide the desired slushy texture without watering down the drink too much. If you're using fresh strawberries, freeze them for at least 2-3 hours before blending. Gather your lemonade, ice, sugar (or simple syrup), and any desired garnishes.

Step 2: Combine the ingredients. Add the frozen strawberries, lemonade, and ice cubes to a high-speed blender. Ensure the blender is sturdy enough to handle frozen ingredients to prevent damage.

Step 3: Blend until smooth. Pulse the blender a few times to break up the ice and strawberries. Then, blend on high speed until the mixture is completely smooth and slushy. This may take a minute or two, depending on the power of your blender. You may need to stop and scrape down the sides of the blender with a spatula to ensure even blending.

Step 4: Sweeten to taste. Once the mixture is smooth, taste it and add sugar (or simple syrup) to adjust the sweetness. Start with 2 tablespoons and add more to your preference. Remember that the sweetness of the strawberries and lemonade can vary, so adjusting the sugar is essential. Blend again briefly to incorporate the sugar.

Step 5: Serve and garnish. Pour the Frozen Strawberry Lemonade into tall glasses. Garnish with lemon wedges, fresh strawberries, and mint sprigs for an extra touch of visual appeal. Serve immediately and enjoy the refreshing taste of summer!
