To start be sure the lemons are at room temperature. If you keep them in the refrigerator allow them to sit over night so they are easier to juice.
Roll the lemons on the counter with your hand before you juice.
You can use a hand juicer however it is hard on your hands. We prefer an electric juicer. We purchased an attachment for our kitchen aid mixer and it works well.
Juice your lemons
Make sugar-water by boiling water with an equal amount of sugar (I have also used all natural maple syrup and that works really well too)
For 1 gallon of lemonade use 2 cups sugar-water and 4 lemons
Add lemon juice while sugar water is hot.
If it tastes too sweet, add more water. If it tastes too sour, add more sugar-water. If it tastes too weak, add more lemon juice.
If you have left over lemon juice freeze it into an ice-cube tray.
Refrigerate and serve with ice and lemon slices for garnish, if desired.
You can see the chart below for Sweetleaf Stevia if desired instead of sugar. If you use all natural maple syrup use desired for your preference.
