1/2 cup sugar or sweetener you can cook with, like Ideal
1/2 cup water
At least 1 cup freshly squeezed lemon juice
Club soda or seltzer water plus a pinch of salt
Bring sugar and water to a boil to make a simple syrup. Let cool.
In a pitcher with plenty of ice, pour in lemon juice. Add at least 1/2 of the syrup. Stir. Pour in at least 8 ounces carbonated water. Taste. Adjust to your preferences. Some like lemonade with hardly any sweetness at all, so they would add more lemon. Some may want more syrup. Some may want more carbonated water.
Garnish with lemon slices, mint or basil.
