1 part freshly squeezed lemon juice
1 part sugar (slightly less for more pucker)
7 parts water
Optional: a pinch of salt. Courtesy of Miss M who is convinced it is the secret ingredient.
(Note: One lemon gives about 1/4 cup of juice.)
(1 cup juice makes 2 quarts lemonade)
Here is what we did.
We used 1/2 gallon apple juice bottles. Put one cup juice, one cup sugar, a bit of salt, and a couple cups of warm/hot water in each bottle. Screw the lids on tight and let the kids shake until the sugar is dissolved. Add some ice to cool it down. Top off with water. Shake again to mix.
