Hi there,
The only real way to get a cherry jam or jelly to set is to add a pectin to
the mixture especially if you are using honey. Choose a recipe which uses
either liquid or powdered pectin as this helps the jam or jelly to set (some
recipes use agar-agar) and then you will have to adjust the water content to
replace sugar with honey. It is quite complicated and a matter of trial and
error.
I have played about with a number of recipes but am not familiar with your
type of cherries. I will have a look and see if I have a more specific
recipe but roughly if you replace the sugar with three-quarters the amount
of honey that is reduce the quantity by a quarter and reduce the liquid
content by a fifth it should work.
Also I have now looked in a copy of 'Putting it up with Honey' by Susan
Geiskopf on page 50 there is a recipe for Blackberry Jam with suggestions
that you may also use chokecherries instead. If you need further
information on this please contact me direct.
