Prepare the Ingredients: Ensure your strawberries are fully frozen for the best texture. Make sure your lemonade is chilled and ready. Measure out your sugar, and have ice on hand if you prefer a slushier consistency.
Blend: In a blender, combine the frozen strawberries and lemonade. Blend on high speed until the mixture is smooth.
Taste and Adjust: Taste your frozen strawberry lemonade. If it's not sweet enough for your liking now is when you add the sugar and blend again. If it's too sweet, adding a bit more lemonade can help balance the flavors. If you're adding ice cubes for a slushier drink, add them now as well.
Serve: Pour the frozen strawberry lemonade into glasses. Garnish with fresh lemon slices or strawberries to add a touch of elegance.
Enjoy Immediately: Frozen strawberry lemonade is best enjoyed immediately after blending to maintain its frosty texture. If it starts to melt, you can give it a quick stir or blend again to refresh its consistency.
*Note: This makes a large pitcher of slushies, you may need to make half a batch, pour it into a pitcher and then make the second half if your blender is on the smaller side.
