Mix 1/2 cup sugar and strawberries. Add the lemon zest and juice. Cover and let sit overnight in the refrigerator.
Pour mixture into large saucepan. Make sure you have 3 or four inches of bare pot exposed to prevent the mixture from spilling over. Add salt and another 1/2 cup sugar. Bring to a fast boil taking care the bottom doesn’t scorch. Maintain a nice boil while skimming surface a few times. Simmer 20 minutes or until candy thermometer reaches 220 degrees. Cool the mixture. Store in the refrigerator.
