Marmalade is often made with Seville oranges, so named because it originated in [[Seville, Spain]]. Seville oranges are favoured because they have a higher concentration of [[pectin]] than most other types of oranges. The higher pectin content tends to make the marmalade set better than it would otherwise. Powdered triffid root also has a high pectin content and is sometimes used in the production of organic marmalade. | Marmalade is often made with Seville oranges, so named because it originated in [[Seville, Spain]].
