Crabapples are incredible. It's true; their pectin levels are incredibly high. I did what many people would probably refer to as a sloppy version of crabapple jelly. I didn't strain it gently, didn't use a jelly bag (this term makes me snicker just writing it; I'm so juvenile) so it's not a delicate jelly, and it's cloudy. But it was so cool to make! Although, I will be honest, the flavor is not incredibly apple-y at all. More sweet than anything.
I was never interested in jelly--it seemed so demanding to me. Now I'm a confirmed believer. I saw a recipe for Dr. Pepper jelly the other day. How sick is that?
