High Quality Content by WIKIPEDIA articles! Marmalade is a fruit preserve, made of orange or other citrus fruit, sugar, and water. Recipes include some amount of peel and zest, which imparts a sharp, bitter taste from the bitter citrus oil. Scottish marmalade is made from oranges and contains more peel and zest than most other marmalades. Central European and California-style marmalade contains less peel and zest and so is less bitter. In languages other than English, marmalade can mean preserves made with fruit other than citrus. The recipe includes sliced or chopped fruit peel simmered in fruit juice and water until soft; indeed marmalade is sometimes described as jam with fruit peel (although manufacturers also produce peel-free marmalade). Marmalade is often eaten on toast for breakfast. The traditional citrus fruit for marmalade production in the UK is the "Seville orange", Citrus aurantium var. aurantium, thus called because it was originally imported from Seville in Spain;it is higher in pectin than sweet oranges, and therefore gives a good set. Marmalade can be made from lemons, limes, grapefruits, oranges or any combination thereof.
