I've never used one of these and I was just wondering if they came ready made
in the supermarkets. Every thing seems to be premade today, so why not this
;-). I know they have soup greens pre packaged. Hate to buy full bunches of
herbs when you just need a bit as they are expensive, and have no idea where to
get cheesecloth. Can you make several in advance and freeze them, if they can't
be bought premade? Any advice on this?
