Squeeze enough lemons to equal 1 cup lemon juice. Place the lemon juice and 1 cup strawberry simple syrup in a pitcher, then add 4 cups water(or more to taste). Stir to combine. Adjust the amount of syrup as needed.
Store leftover lemonade in an airtight glass container in the fridge for up to 5 days.
Notes
How to choose lemons. Not all lemons are created equal. The best lemons for lemonade feel heavy because they are full of juice. I especially like Meyer lemon juice for lemonade because their juice is milder and sweeter. Any type of lemon will work.
Roll the lemons before juicing. Give each lemon a firm roll on the countertop before juicing it to help break down the membranes inside. This will give you more juice!
Adjust to taste. I used 1 cup of simple syrup in this recipe and found it plenty sweet. Definitely add more or less to your taste. You can start with ½ cup of strawberry simple syrup and go from there.
Chill. I like to chill my homemade lemonade in the fridge for at least 30 minutes before serving. Or, serve it over ice if you can't wait.
Make a cocktail. Use strawberry lemonade as the mixer in a summery cocktail. Pair it with bourbon, vodka, or gin.
Or a mocktail. Add a splash of sparkling water (flavored or unflavored) to turn this into a fizzy strawberry lemonade mocktail. Garnish each glass with a strawberry slice and a sprig of mint.
Double up. You can easily double or triple this recipe to make a lot of strawberry lemonade!
