What is Jam and Marmalade?

• Jam is basically a sweet spread made by cooking fruit in sugar and water until set.
• Jam is made from whole fruit that is either crushed or chopped and so differs from conserve, in which the fruit or fruit pieces remain intact.
• The setting power depends on the pectin content of the fruit (pectin occurs naturally in many ripe fruits).
• Some fruits that are abundant in pectin include apples, blackberries, lemons, oranges, and black currants.
• One of these can be combined with a strong-flavoured fruit which is low in pectin to produce a good-setting jam.
• Marmalade is similar in preparation to other jams, but only citrus fruit (either a single fruit or a mixture) is used.
