Sort the raisins, rinse, pour hot water for 10 minutes. Drain the water in a colander. Peel the apples, cut them into small cubes, and cut the orange into medium cubes (I took a “honey orange in powdered sugar”, it is also called Fortunella or kumquat, by the way, it strengthens the immune system).
Mix everything in a saucepan or saucepan, add oil, simmer over low heat until the apples are soft (if the apples are soft enough, for 7 minutes, firm a little more), add starch, warm up, stirring. Remove from heat and cool.
