The message
from "shannie" contains these words:
Another tip for jam making, if you can't be bothered with all the fiddling
with wax paper, cellophane and annoying little elastic bands that fly
accross the kitchen, get some suet from your local butcher, melt it down,
pour off the oil that results from that on top of your cooled jam, it sets
hard as its a form of tasteless and odourless lard and it keeps all air out
as it settles all round the top of the jam. A bit time consuming and you
need lots of suet but my jams keep for over a year and not a bit of mould
forms
Shan
I`m printing that tip off Shan!
