Marmalade is a type of fruit spread made from citrus fruits like oranges. You may imagine everyone in England eating toasted crumpets with orange marmalade and tea for breakfast every morning.
Marmalade is essentially a type of jam that includes peels and rinds. Though plenty of sugar is used in making marmalade, the presence of citrus peels gives it a tart or even sour flavor. One of literature's most famous lovers of marmalade is Paddington Bear, who traveled to Britain from Peru and claimed, "I came all the way in a lifeboat, and ate marmalade. Bears like marmalade." The word stems from the Portuguese marmelo, "quince."
