The history of sweetened, preserved fruit, be it jams, jellies, preserves or murabbas, traverses a path just like that of many meals we now take without any consideration. They began out as the unique protect of the royals and the elite, solely changing into mass-manufactured and inexpensive in current centuries.

Preserving seasonal fruit via the addition of sugar is an historic method. As far again as 50 CE, in his work De Materia Medica (Greek for On Medical Material), the Greek doctor Pedanius Dioscorides wrote of quince preserved in honey. As sugarcane cultivation unfold in Asia, royal kitchens from these of King Khosrow II of Persia (seventh century CE) to these of France’s Louis XIV (seventeenth century CE) served fruit preserves with pleasure, from quince murabba to cherry jam.

Sugar was costly; information point out that in 14th-century England, a pound of it price the equal of a talented workman’s weekly wages. So it wasn’t utilized in giant portions in common kitchens till the 18th century.

The excessive ranges of sugar bind the water molecules, inhibiting microbial progress. The sugar additionally attracts water away from the pectin molecules, in order that they’ll kind a fragile sponge-like community that holds the jam collectively.

Whether home made or business, the sugar in jams, together with the low pH of the fruit and the sterilisation of jars, is sufficient to produce a shelf-stable product. So keep away from shopping for jams that record preservatives similar to potassium sorbate (E 202) or sodium metabisulfite (E 233); and elements similar to synthetic flavours and synthetic colors. They are pointless in a jam.

A sugar-free jam may have an extended record of elements similar to maltodextrin or polydextrose, and preservatives similar to potassium sorbate.
