Marmalade is a citrus preserve made by cooking fruit pulp, juice, and peel with sugar until it sets, most often from Seville (bitter) oranges but also from lemon, lime, grapefruit, or other citrus. It differs from jam in that it includes the fruit's peel, which gives marmalade a characteristic bitterness and shredded texture that jam, made from pulp alone, does not have. The name comes from the Portuguese marmelo, meaning quince, reflecting marmalade's origin as a quince preserve before citrus versions became dominant. In Britain it is a breakfast staple served on toast; it is also used as a glaze for roasted meats and poultry and pairs well with strong cheeses.
