I was surprised that there's really only one recipe for Autumn Olive Jam floating around on the internet. While the recipe from Dreams and Bones is perfectly fine, I didn't have no-sugar-added pectin on hand and I didn't want to make a run to the store just for that. Therefore, my Autumn Olive Jam is based on the Ball recipe for berry jams (5 cups of mashed fruit with 7 cups of sugar and regular powdered pectin).
First I washed and drained the berries. Then I cooked approximately 9 cups of berries with one cup water for about 5 minutes (or until mushy).
This glop was run through my squeezo (see it in action here, or here) to remove the seeds and twigs. I only have the apple/tomato screen that came with the food mill and the sizeable Autumn Olive seeds were pushing it to the limit, but it still worked (eventually).
The seeds were incredibly clean after only one pass through the machine. Usually I run stuff through three or four times before this happens (must be the big seeds).
I think the color and texture may be a little off-putting (it kinds of looks like ketchup, or congealed blood), but it tastes good (tart and somewhat unique). It's definitely a novelty jam, but I think some of my like-minded friends will appreciate a jar.
