From the first 1400 grams of lemons, cut off and discard ends of lemons. Cut lemons in half and seed, discard seeds. Cut lemons very thinly. Place in pot and barely cover with water. Bring to boil, boil 5 minutes, drain water and discard. Add juice of two lemons plus enough water to make 8 cups and all the sugar and the salt. Boil until the preserves pass the wrinkle test.

Squeeze lemons and set aside juice. Discard seeds. Cut off and discard ends of lemons. Cut lemons in half and cut lemon peels very thinly. Place in pot and barely cover with water. Bring to boil, boil 5 minutes, drain water and discard drained water. Combine 2/3 of the lemon juice (more or less depending on desired tartness), with enough water to make 8 cups of liquid, and add to the lemon peels with all the sugar and the salt.
