[PW] confusing food terminology

[Edith Bailes]

Marian Drabkin said: Jam
and jelly are as has been described, the first of mashed or pureed fruit
cooked down with sugar and sometimes added pectin so that it is semi-firm if
turned out on a plate, and jelly being the expressed juice of fruit mixed
with sugar and sometimes added pectin, and cooked to the point where it
will, when slid out of its glass, stand up on a saucer.

Reminds me of the Glenn Miller hit "It Must Be Jelly, 'Cause Jam Don't Shake
Like That."
