I picked these crabapples yesterday morning! I drove about 20 mins to a friends house and picked them in the park across the street from her house. There were tons of beautiful, ripe crabapples there! These are the big kind, 1" - 1.5" across! I only need about 15 to 20 lbs to make crabapple wine, which is about two buckets full. I knew there would be a lot of waste, so I picked more than I needed.

The secret to making good jelly from the very tart, wild things is to use only the clear juice, without any pulp in it. Use a very fine strainer or straining bag and do not squeeze it. This includes, but is not limited to, rhubarb, wild grape, crabapple and choke cherry (which I fully intend to make next year). It probably also includes wild strawberries and a few other things as well.
These things usually have a lot of acid or tannin which is what makes them so tart. So I don't usually add acid to the recipe, although I will for the crabapple, I think. Raw apples, as a general rule, are low in acid. I have a new acid tester now, so I can test the finished juice after boiling and straining and add just the right amount of sugar to it.
I have enough to make crabapple jelly! (It's TIME that I don't have!) Maybe I will just put those in the freezer for now and make jelly later. No pectin is needed for apple jelly. Apples have a lot of their own pectin. As a matter of fact, you can make pectin for general use from apples and crabapples, if you have enough.
Crabapple Jelly Recipe
8 cups fresh crabapples
water as needed
3 cups white sugar
1.Remove stems and blossom ends from crabapples, and cut into quarters. Place them in a large stainless steel or other non-reactive pot or saucepan. Add enough water to be able to see, but no so much that the crabapples are floating. Bring to a boil, reduce heat to medium, and let simmer for 10 to 15 minutes. The apples should soften and change color.
2.Strain the apples and juice through 2 or 3 layers of cheese cloth. Do not squeeze. Use just the clear juice. You should have at least 4 cups of juice. Discard pulp, and pour the juice back into the rinsed pan. Bring to a simmer, and let cook for 10 minutes. Skim off any foam that comes to the top. Next, stir in the sugar until completely dissolved. Continue cooking at a low boil until the temperature reaches 220 to 222 degrees F (108 to 110 C). Remove from heat.
3.Pour the jelly into sterile jars leaving 1/4 inch headspace. Process in a hot water bath to seal.
