Take each peach and with a sharp knife cut an X into the bottom of the peach at the tip. Place the peaches in boiling water for about 1 minute.
Remove from the water and immediately plunge the peaches into an ice bath to stop the cooking. Then carefully remove the peel, pit and chop the peaches finely.
Measure out exactly 5 cups.
Place jars, rings and lids into a pan, cover with water, bring to a boil and boil for three minutes to sterlilize, keep warm.
In a heavy stock pot, place the chopped peaches, lemon juice, ginger, curry, salt, fruit fresh (if using) and butter. Mix everything together well.
Measure ¼ cup of sugar and mix it with the contents of the Sure-Jell. Sprinkle it into the peaches, mix well again and set it on the stove on high and bring to a boil, stirring constantly.
When it comes to a hard boil (a hard boil is one you can't stir down with spoon) add the remaining sugar.
Continue stirring constantly and return it to a boil and when it comes back to a hard boil, continue boiling it for exactly one minute. (Set a timer to make sure you get it for a full minute).
Remove from the stove & immediately ladle into sterilized jars. Place lids on jars, screw on tightly. Process in a hot bath (boiling water) for 10 minutes to seal the jars.
