Make simple syrup by combining the water and sugar in a saucepan over medium heat, stirring until dissolved (1-2 minutes). Let it cool completely in the fridge (or freezer if you are in a hurry). It should make about 1.5 cups of simple syrup.

Use a lemon juicer to squeeze the juice from your lemons and then strain the lemon juice to remove the seeds and pulp. Press and squish the pulp down in the strainer to make sure that you get all the juice out of the lemons.

Pour the juice into a pitcher and mix with the five cups of water. Add the simple syrup - start with about a cup of it and test the lemonade for sweetness. Add more as per your taste.

Muddle a few raspberries and mint leaves in each cup. Add ice. Pour the lemonade on top and give it a gentle stir. Alternatively, you could muddle all the raspberry and mint a pitcher and then pour the lemonade over if you want to serve the whole pitcher at once.

Garnish with a lemon or mint leave, and add a straw. Enjoy!

You could also make this a delicious summer cocktail by adding a jigger of vodka to the glass before you add the lemonade!
