marmalade
 

Orange marmalade has long been a favorite spread for breads and toast.
You may be surprised to learn that marmalade was originally made from
a completely different fruit, one not even in the citrus family.
Marmalades are used not only as a sweet spread, but also as a main
ingredient in a variety of breads and desserts as well as in sweet and
savory sauces for meat, poultry, and vegetables.
