4 large springs spearmint
4 large springs lemon balm/melissa
1 C fresh-squeezed lemon juice
1 C fresh-squeezed lime juice
1 1/2 C sugar
1 C warm water
5-6 C cold water, depending on how strong you like your lemonade
Dissolve the sugar in the warm water, adding more water if needed to dissolve. Muddle the mint and lemon balm in your pitcher and add in the sugar water and citrus juices. Mix well. Top of with as much very cold water as you want. This is great made a little stronger (i.e. less cold water) and then diluted with some sparkling water right before serving.
Also, instead of about a 2 cups of the water you could add in some plain or lemon vodka and/or even replace some of the sugar with limoncello liqueur for a more adult drink. On the rocks, topped off with fresh lemon slice and mint spring and soda water, this makes an amazing cocktail.
