A fruit preserve made from the juice of a citrus fruit and peel is referred to as Marmalade in modern day Britain. Whereas other fruit preserves are called jams. But there’s no clear difference between jams and marmalades.
It is believed that marmalade may have been derived from the Portuguese word “marmelo” which means quince jam.
The earliest known records of marmalade can be referred back to 1524 when Henry VIII received a “box of marmalade” from Mr Hull of Exeter. Eliza Cholmondeley’s recipe book from 1677 refers to “Marmelet of Oranges”.
There are different forms of recipes to preserve fruits – Marmalade, Jam (whole fruits in sugar syrup), Compote (fruit is boiled with 10% or 15% of its weight in sugar), Jelly (made from boiling juicy fruits containing pectin with sugar).
