Why hello, there, adorable little plums! I almost mistook you for grapes. I’m sure glad I didn’t, because you are as delicious as you are precious. Yes you are!
New to me, I’d never heard of a Damson plum before. But luckily I didn’t pass them by when I saw the basket at the farmers market, but rather stopped and took a closer look. And then bought some. With no particular plans in mind.
It’s no surprise they ended up as jam. What was a surprise was how rich and flavorful the jam was. The plums themselves were nothing extraordinary. Slightly tart, not very flavorful, nothing like a regular plum which can be incredibly succulent and juicy. But the resulting jam is filled with a rich fruityness that, if I hadn’t actually made the stuff, I’d never guess it was made from these lackluster little plums.
I see this gorgeously rich purple jam spread onto toast for a mid-morning snack; mixed with some exotic spices and used as a sweet and savory marinade; warmed and drizzled over vanilla bean ice cream.
You know what? This unexpected jam might just be my favorite one yet. All because of a surprise market find and an on-a-whim purchase. Fate? Perhaps. Delicious? Most definitely.
Damson Plum Jam
3 pounds damson plums, pitted and quartered (can also substitute other plums or pluots)
3 cups granulated sugar
1/2 cup lemon juice
In a large nonreactive bowl, gently toss together the plums and sugar. Cover and let stand at room temperature for at least 4 hours or in the refrigerator overnight (but if you’re pressed for time, 30 or 40 minutes will do you just fine!).
Prepare canner and wash/sterilize 6 half-pint mason jars. Keep jars in hot (not boiling) water until ready to use. Place 2 or 3 small plates in the freezer.
Transfer the plums to a large nonreactive saucepan and add lemon juice. Bring to a boil over medium-high heat, then reduce heat to medium and cook, uncovered, for 10 minutes, stirring frequently. Spoon 1 teaspoon of jam onto a chilled plate to test if the jam is ready (the jam is ready if it wrinkles when nudged gently with a finger). If it isn’t yet ready, continue to cook for 1 to 2 minutes, then test again on a clean plate.
Ladle hot jam into jars, leaving 1/4-inch of headspace. Remove any air bubbles and adjust headspace, if necessary. Wipe the rims clean and top with lid; screw on ring until finger tight. Process in a boiling water bath for 10 minutes. Remove from water and let cool completely, 12 to 24 hours. Check seals. Any unsealed jars should be refrigerated and used within 1 month.
Bonus! I always design them (naked jars have no place in my home), so I may as well share them. These labels compliment this rich purple jam perfectly. Simply print and stick and voila! Pretty pretty package.
