I am getting confused with the words Jam/ Jelly - Which is the one made from cooking fruits and which is the one made from Gelatine?
Which is AmE and which is BE, well and what shall I call each of them?
The thing to watch is that 'jelly' on its own (not preceded by the name of a fruit) is in BE a sweet, usually cold dessert - often served with ice-cream. 'Jelly and ice-cream' is traditionally served at children's parties. I believe this is 'jello' in AmE.
I mean fruits like oranges, lemons, lime, grapefruit. Strawberries also contain citric acid, and you can't have Strawberry marmalade.
[It's much less common, according to Google, on UK-only sites; but it still exists.]
Jam is fruit preserved by heating to a high temperature with sugar and with the fruit retained.
Jelly is the juice strained off fruit which has been prepared in this way, and then allowed to solidify.
The dessert/pudding Jelly is made from gelatine with fruit flavourings. (US = Jello)
Jelly is the wobbly one.
