1 cup water
1 cup sugar (can reduce to ¾ cup)
1 cup lemon juice from 4-6 lemons
3-4 cups cold water
Make a simple syrup by heating the water and sugar in a small saucepan until the sugar is dissolved completely. While the sugar is dissolving, use a juicer to extract the juice from 4 to 6 lemons, enough for one cup of juice. Add the juice and the sugar water to a pitcher. Add 3 to 4 cups of cold water, more or less to the desired strength. Refrigerate 30 to 40 minutes. If the lemonade is a little sweet for your taste, add a little more straight lemon juice to it. Serve with ice and sliced lemons.
