Lemonade
Peel zest from 2 lemons and cut into thin strips. If necessary remove any bitter white pith with a sharp knife.
Boil zest, 2 cups of sugar, a pinch of salt and 1 cup of water for 5 minutes. Remove from heat and add a few fresh mint leaves. Steep for 10 minutes. Strain and place in the fridge or freezer to cool completely.
Collect the juice from 6 lemons.
Mix together fully cooled syrup and lemon juice to make lemonade syrup. Combine this syrup with water or club soda. I like a ratio of approximately 1 part syrup to 5 parts water, but taste it and see what you like.
Although mint is delicious it can be fun to mix things up sometimes. Here are some variations:
Citrusade:
Experiment with replacing some or all of the lemons with other citrus.
Vanilla Lemonade:
If you've never tried this, it is really interesting and delicious. Either boil half a vanilla bean with the syrup or add a slash of vanilla extract to the cooled mix.
Rosemary Lemonade:
Steep a few sprigs of rosemary in the hot syrup instead of mint.
