I was given a large amount of lemons and am trying to find a tested lemonade concentrate (or lemonade or lemon syrup) recipe to use to water bath can them. I have already done some using the Ball Strawberry lemonade concentrate, as well as salt preserving others but still have a lot left over. I am finding some lemonade recipes calling for a 1:1 ratio (1 cup fresh squeezed lemon juice, 1 cup sugar + 6 cups water) heated to 190 degrees and water bath canned for 15 minutes for pints. Does that sound right or do you know of any resources or tested recipes?
