The array of powdered drink mixes on the market may make you opt for convenience over taste, but lemonade made from real lemon juice has a more intense, fresher flavour. With lemon juice concentrate you can make a homemade lemonade tailored to your tastes without the hassle of juicing lemons. If you're concerned about calories and sugar, you can substitute the sugar with low-calorie sweetener.
Pour 3/4 cup of sugar or granulated sugar substitute into your 2 qt. pitcher. You can always add more later if it is too tart, but start with 3/4 cup.
Shake the container of lemon juice concentrate before using. Pour 1 cup of juice into the pitcher.
Add 6 1/2 cups cold water and mix thoroughly. Taste. If necessary, add up to 1/4 cup sugar (or more, depending on your preference).
Add 1 cup of ice cubes and stir.
Pour into tall serving glasses or tumblers.
Serve immediately and store any leftover lemonade in the refrigerator. Add four or five thick slices of lemon to the mixture for better appearance and flavour.
If you add lemon slices to your lemonade, wash the lemons well beforehand to avoid food-borne illnesses.
