Jam contains both fruit juice and pieces of the fruit‘s flesh, however some cookbooks define Jam as cooked and gelled fruit purees. Properly, the term jam refers to a product made with whole fruit, cut into pieces or crushed. The fruit is heated with water and sugar to activate the pectin in the fruit. The mixture is then put into containers. The following extract from a US cookbook describes the process. " Jams are usually made from pulp and juice of one fruit, rather than a combination of several fruits. Berries and other small fruits are most frequently used, though larger fruits such as apricots, peaches, or plums cut into small pieces or crushed are also used for jams. Good jam has a soft even consistency without distinct pieces of fruit, a bright color, a good fruit flavor and a semi-jellied texture that is easy to spread but has no free liquid. " - Berolzheimer R (ed) et al (1959) What is Jam?

Preserves The term Preserves is usually interchangeable with Jam , however some cookbooks define Preserves as cooked and gelled whole fruit (or vegetable), which includes a significant portion of the fruit Marmalade British-style marmalade is a sweet preserve with a bitter tang made from fruit, sugar, water, and a gelling agent. American-style marmalade is sweet, not bitter. In English-speaking usage "marmalade" almost always refers to a preserve derived from a citrus fruit, most commonly oranges. The recipe includes sliced or chopped fruit peel, which is simmered in fruit juice and water until soft; indeed marmalade is sometimes described as jam with fruit peel. Variants of Jam Continues…

Jelly In the U.S. and Canada, the term jelly refers to a type of clear fruit spread consisting of firmed fruit (or vegetable) juice made with pectin. In British English, these products are commonly referred to by the terms fruit spread or preserves , although jelly is also used in some instances, for example mint jelly. Jelly can be made from sweet, savory or hot ingredients. Jelly is made by a similar process to jam, with the additional step of filtering out the fruit pulp after the initial heating. A cloth "jelly bag" is traditionally used as a filter. Variants of Jam
