Jam with oranges and rhubarb for winter

To make rhubarb jam, wash the rhubarb in cold water, clean it (you don't have to clean it, I leave the skin, because it's full of vitamins), cut into bars about 0.5-1 cm. The bars are laid out in an even single layer on a baking sheet and dried in the oven for about 15 minutes, stirring occasionally.
During this time, thoroughly wash 3 oranges, remove the peel (or the whole orange) finely, finely cut or scroll through a meat grinder.
Pour the dried rhubarb into a saucepan and cover with sugar, put our oranges there and cook for about 5-8 minutes in 3 doses (boiled for the specified time, stirring, turned off, cooled). That's it, then we seal it in sterilized jars and enjoy such jam in winter (well, if it lasts until winter =))
