silky wild plum jam

IMG_3945Well, the bright side is that I keep getting tiny signs from the universe that there’s a branch over my head just laden with juicy, impossibly blueberry bloomy blue fruit, ripe for the plucking.  It’s just a matter of timing and overcoming myopia and finding a stable ladder. I’m trying, and so far I’ve been pelted on the head a few dozen times and threatened by an overhanging spider and infested with earwigs and ants enjoying their lunch.  I’m pretty sure something dropped down into my bra and bit me where the sun don’t shine.  But always a little fear in pleasure, in possibility.

So. Jam. To measure the sugar you need and get a sense of the yield, you’ll need to imagine how the plums will reduce to a purée once cooked. I filled a standard colander with 5 and a half pounds of small plums, and used 4 cups of sugar in a single 5-quart pot. It yielded 7 half-pints. Your needs will vary.

This jam is all about found fruit, especially the ornamental “cherry plums,” the golfball-sized drupes that cover those pesky feral plum trees that spring up all over the place, including your yard. I had a yellow one in Berkeley, cut down a red one in my yard in Eugene, understood when the neighbors cut down the burgundy-foliaged one in their yard.  It also works for Damsons or Santa Rosas or any juicy, smallish fruit fresh from the orchard.  The recipe is adapted from Linda Ziedrich‘s damson plum recipe, in fact.  I kept the flavor simple, as it really can’t be improved.  You might add a slug of slivovitz at the end, or perhaps a tiny bit of clove.

You won’t be cooking this one terribly long, a blessing in the heat. Plums have plenty of pectin; that’s the silky texture. Wild plums have clingstone pits, so plan on cooking them in and straining them out later.

Silky Wild Plum Jam

I like what plum skins do to jam, coloring and flavoring it, but if you strain them out with a food mill, the jam will be a wonderful soft, clean, pure texture — perfect on skin, as a friend says.

  • Small cherry plums
  • Sugar (3/4 cup per cup of plum purée)

Rinse ripe plums just after picking, and place in covered pot with a bit of water (no more than a half cup).  Simmer for about 10 minutes until the skins burst, then uncover and stir, pressing the flesh down with a spatula or spoon. Simmer for another 10 minutes until plums have fallen apart.  Pits may or may not rise to the surface.  You will be lucky if they do.

Remove from heat and let cool enough to handle.  Skim, strain, and squeeze the pulp from the skin and pits.  You might try a mesh colander or a food mill.  This process may be difficult and messy, as some plums won’t yield up their pits easily, so you may find even a food mill ineffective.  If worse comes to worse, don a pair of food service gloves and pluck the pits out with your fingers, squeezing them to get all flesh off.

Once you have a pot full of delicious pulp, measure it.  For each cup of pulp, add 3/4 cups of sugar and begin the jam process.

Wash your jars, rings, and lids, and heat the lids according to the package instructions as you’re heating up the waterbath canner.

Cook jam down over medium high heat until it thickens and passes a gel test (perhaps 15 minutes?), stirring very frequently and scraping the bottom of the pot.

Remove from heat and let sit for a couple minutes.  Skim foam from top. Spoon the hot jam into jars carefully to reduce bubbles, leaving 1/4-inch head space.  Wipe rims of jars and adjust lids and rings.  Process in a waterbath canner for 10 minutes.

    I’m definitely bookmarking this one for next June, which is when our backyard cherry plums start falling all over the place. :)

    I juiced our ornamental plums this year–delicious–but next year it may be jam!
