Marmalade is a fruit preserve that is most often spread on toast. It is made with citrus fruit, sugar, water and added pectin when needed. British marmalade, much of which is made in Dundee, Scotland, is bittersweet, whereas the American-made version is just plain sweet.

The Seville orange is widely used to make British marmalade, as it is higher in pectin than a regular orange and helps the marmalade to set naturally once pectin is released by boiling the fruit and sugar.

Marmalade comes in variations according to how thick you like the cut of the peel. Marmalade can also be made with grapefruit, limes, lemons or clementines.

You can also spread marmalade on sandwiches or scones; mix it with whipped cream and spread it between layers of cake; or mix it into a marinade for chicken or pork.
