Cherries
Alcohol of choice

Fill a Jar with cherries. Add alcohol to cover all the cherries. Let sit
for a week or so, by this time the cherries should have swelled and there
should be less liquid in the jar. Pour off the liquid. a) Layer the
cherries with sugar and let sit another week. b) Pour off resulting fluid.
c) Repeat steps a) and b) until the cherries are so small that theyre just
basically the pit covered with a very thin skin.

Now mix all the batches that you poured off to suit your taste. The first
is most bitter, the last is the sweetest.
