Apple Jelly: Where's the jam?

Jelly is actually the American way of referring to good ol' jam!

Mystery solved - end of blog.

No, seriously, Apple Jelly really is a type of jam and not that wobbly, fluorescent coloured, transparent goo. So why isn't it just called jam?

Well, the reason is that jelly is made in a slightly differently manner than jam.
While jam has the fruit suspended in it, giving it a chunky consistency, jelly is made by extracting the juice from the fruit and then using that to make the jelly (read jam). And that's why jelly has that gorgeous glistening clarity.

So which one is better? Jam or Jelly? 
Can't say - it wouldn't be an 'apples to apples' comparison. (Pun unintended)

Is one healthier than the other?
Not per say. The only thing jam has over jelly is fibre.
