How to make jam from the raspberries?

        FIRST WAY. Raspberries pour in layers granulated sugar (for 1 kg of berries - 1 kg of sugar) and put in a cold place for 12 hours. Then add half a glass of water and put on low heat. Cook until done in one step, remove the foam. Before the end of cooking to preserve the color of berries, add 2-3 grams of citric acid.
