Thanks for that article,
ElizabethB!
When I started my jam/jelly/marmalade/chutney biz in 2004, I was only interested in getting products sold, but as time went on, I began to investigate a little more about what I was actually making. It´s all highly confusing, and to be honest - who cares as long as it tastes good?


Anyway....
Jam is what Brits describe as a fruit preserve, and what is known as jelly in the US. A peanut butter and jelly sandwich would be called PB & jam in the UK.
So a jelly is, strictly speaking, a form of "jam" where the fruit is sieved and the pips/seeds are removed. The use of the word "preserve" (which can apply to jam, jelly AND marmalade) appears to be more common in the US - but I´m pretty sure I´ve seen "preserves" in the IK as well.
To complicate matters, we´ve also got "Pepper Jelly" - made with hot or bell peppers and with added vinegar; and pectin.
The word "Marmalade" comes from the Portuguese word
marmelada meaning quince jam. It´s used these days for Citric Fruit jams ( Orange, Lime, Lemon marmalade) where the cooking process involves much larger amounts of water.
"Chutney" is an Indian condiment which usually (but not always) contains fruit, spices, sugar and some form of acid: vinegar, lime juice, tamarind water. There are also fresh chutneys, made with yoghurt, coconut, or spices; no vinegar involved.
