Marmalade is a type of canned product that is prepared by boiling citrus fruits with water and sugar, and usually an agent such as gelatin is added to make it jelly. In marmalades, we either chop or puree the fruits. In marmalade, because the cooking time is short, the aroma and flavor of the fruit is preserved better. Marmalades can be stored in the refrigerator for a year if stored carefully and correctly in sterilized jars. In simpler terms, marmalade is a pasty or jelly-like jam that does not contain any pieces of fruit (the fruits are grated or chopped).
