This fragrant, sweet and delicious confiture will be a great addition to a cup of tea, and it can also be placed in small jars and used as a Christmas gift.
Wash the oranges thoroughly and cut them into half rings (along with the peel!).
It is best to take oranges with a thick peel, candied fruits are tastier from them.
Take out the bones in the process, but do not throw them away!
Weigh the mold in which you will cook the jam, and write down its weight.
Put the sliced oranges in a saucepan, pour cold water, wrap the bones in cheesecloth and add to the oranges. Leave it all overnight (or for 12 hours).
Then put the pan on the fire, bring the contents to a boil and cook over medium heat for 40 minutes, then leave for a day.
Remove the bones from the pan.
Weigh the mold with oranges and water, subtract the weight of the mold and add as much sugar as its contents weigh.
Return the pan to the heat, bring the future jam to a boil and cook again for 40 minutes. It should thicken. If not, you'll still have to boil the oranges a little.
Arrange the orange slices in jars and pour the syrup.
In sterilized jars, the jam will be stored for a year or more (in a dark, cool place). I haven't tested it in practice because we've been eating it for a couple of months.
