Citrus marmalade is a classic preserve made from whole fruits — peel, flesh, and juice — cooked with sugar to a semi-set consistency, with a characteristic slight bitterness that sets it apart from jam or jelly. The marmalade tradition is closely associated with bitter Seville oranges, but the Romanian home version uses regular oranges, lemons, and grapefruit to create a balanced marmalade with a complex flavor, rich in natural pectin and vitamin C. Excellent on buttered toast, in pastries, glazes, or as an accompaniment for duck and pork dishes.
