Combine the strawberries, water and sugar in a medium saucepan. Heat the mixture just until the liquid starts to simmer. Leave it on a gentle simmer for 30 minutes and then remove from the heat. Pour the mixture through a sieve, and using the back of a spoon, gently squeeze the juices from the strawberries. Stir in the lemon juice. Allow the mixture to cool for 15 minutes. Taste and add more sugar and lemon juice as you like. How much sugar you need to add will depend on the sweetness of your strawberries.
Serve in a pitcher with ice, some quartered strawberries and a few sprigs of fresh mint as garnish. So refreshing on a warm summer day.
This lemonade is also great as a base for a fun cocktail. Check out my vodka strawberry lemonade recipe.
