Zucchini peel and seeds and cut into medium-sized cubes, orange and lime wash well and cut together with the peel of a cube or small plates, ginger peel and cut into small strips. If you don't have lime, replace it with lemon.
Put all the ingredients in a saucepan, in which we will cook, pour the sugar and mix. To your taste, the amount of sugar can be reduced or added. My jam came out quite sweet.
Put on the fire, bring to a boil, reduce the heat to medium or slightly less, and cook for 30-40 minutes, until all the pieces are transparent.
Ready jam still hot pour into jars, and you can cool and serve with tea. Fragrant, fragrant jam, with a slight bitterness of citrus zest and a subtle aftertaste of ginger will be a great addition to cheeses, and will be simply indispensable for the prevention of colds!
