Wash the oranges. To remove wax, pour boiling water over them. Cut the peel into beautiful slices: first cut it in half, and then into slices. Prepare a needle and a long strong thread. Twist each piece with a snail, pierce it with a needle and put it on a thread, making “beads”. Fill the peel, strung on a thread, with cold water, which must be changed three times a day. The “beads” are soaked for 3 days so that the crusts become soft and stop being bitter.
Boil the soaked peels for 20 minutes 3 times, each time filling them with fresh cold water.
Cook syrup from the specified amount of sugar and water. Place orange peel and string into it and cook until the syrup becomes thick like liquid honey. Finally add citric acid.
When the jam has cooled, remove the string, place the curls from the peel in a clean, dry jar and fill with syrup.
Serve orange peel jam with toast and coffee, or with freshly baked scones and butter.
