First, gather all of your needed lemons for your lemonade. (Try six out for starters).
Juice the lemons, should give you 1 cup of lemon juice. Remember you can get the most juice by firmly rolling the lemons between your hand and the counter. Then cut the lemons in half and juice.
In a gallon pitcher combine 1 cup lemon juice, 1 cup sugar, and 6 cups cold water. Stir, and adjust water to taste.
