i'd stick with vinegar...
I'm fortunate to have blackberries, black
raspberries and mulberries growing in my back
yard.
Even so, if you buy the fruit when it's
cheap and ripe it's MUCH cheaper than
commercial stuff.
I use a gallon jar, (glass or plastic) put
as much mashed fruit as i can manage in it and
just cover with white vinegar. (I have a cheap
juicer which removes the seeds well enough from
black/rasp berries to make a dacqu (i never could
spell that stupid word)... frozen drink) but it
leaves a lot of good stuff with the seeds. I
use the seed/pulp stuff for my vinegar.
Shake the jar daily (this must be Amish
friendship vinegar) for at least a couple of
weeks. Cover the jar first.
Strain mixture through cheesecloth and squeeze
out most of the remaining juice. Bring to a
slow boil, reduce heat, add sugar to taste and
simmer for about 5 minutes. Bottle.
The resulting product is INTENSELY flavored
as well as being beautiful to behold.
I haven't tried peaches from roadside market
time when it's possible to find a peach that
is significantly different from a baseball,
but i will. I wouldn't dream of using the
peach shaped objects that are picked green,
sent to my supermarket and allowed to die
sufficiently to be softish. I might joke with
my postings, but i'm STRAIGHT ARROW, HOWIE
when it comes to my cooking.
IF YOU CAN'T FIND GOOD INGREDIENTS COOK
SOMETHING ELSE!!!!!!!!!! You would be doing
your body and soul a grave disservice. You
might as well put clean socks on dirty feet.
Get my point?
Pheww........It's ok now, my pulse is starting to slow as i type.
