The upside to so many people not using the fruit themselves is that they will often let you scour their trees as well as any you might be so lucky to have. This was my first attempt at Crab Apple Jelly and I would like to thank Suite 101 ( http://fall-recipes.suite101.com/article.cfm/how_to_make_crab_apple_jelly ) for the recipe that I used as my starting point. I changed the recipe slightly however.
Here are the crabapples and lemon zest. I used mostly an orange yellow crabapple with a few very small dark purple crabapples. I do not know the varieties, but the yellow seemed to be a bit sweeter.
Here is the liquid after extracting the juice. A bit cloudy and a pale pink, I reheated it to boiling and then added the sugar.
