I'd be interested to know why one should use 'proper' (and expensive)
jars
instead of ordinary jars.
My whole life I have preserved fruit , made jam, marmalade, pickles,
chutneys etc etc and always recycled jam, coffee, sauce etc jars.


So have hundreds and hundreds of people before you, but some do 'like to be
posh' and be of the 'we only use the proper things don't you know'
