A small-batch mossberry jam that brings together the bright tartness of wild Alaskan berries with the warmth of cinnamon, cardamom, nutmeg, and vanilla. A handful of sweeter berries softens the sharpness of the mossberries, creating a richly flavored autumn preserve that’s lovely on toast, biscuits, pancakes, or stirred into yogurt.
Makes: Approximately 2 cups (two 8-ounce jars)
Prep Time: 10 minutes
Cook Time: Approximately 15-10 minutes
Total Time: Approximately 25-30 minutes, plus cooling
Ingredients
- 1½ cups mossberries, fresh or thawed
- ½ cup mixed berries, fresh or thawed (raspberries, strawberries, blueberries, cloudberries, or additional mossberries)
- 1½ cups granulated sugar
- 2 Tbsp additional sugar, for mixing with pectin
- 1 tsp powdered fruit pectin (setting strength varies by product)
- ¼ tsp citric acid or 1 Tbsp lemon juice
- ½ tsp ground cinnamon
- ¼ tsp ground cardamom
- ⅛ tsp ground nutmeg
- Pinch of fine sea salt (approximately 1/16–⅛ tsp)
- ½ tsp vanilla extract
Instructions
- Prepare the berries
Rinse and drain the berries, then place them in a medium, heavy-bottomed saucepan. Mash gently with a potato masher, leaving some fruit pieces for texture. Stir in 1½ cups sugar, the citric acid or lemon juice, cinnamon, cardamom, nutmeg, and sea salt. In a separate small bowl, thoroughly mix the powdered pectin with the remaining 2 tablespoons of sugar to help prevent clumping. - Cook & thicken
Bring the berry mixture to a full rolling boil over medium-high heat, stirring frequently to prevent scorching. Gradually sprinkle in the pectin-sugar mixture while stirring constantly. Return to a vigorous boil and cook for 1–2 minutes, or according to your pectin manufacturer’s directions. To check the consistency, place a small spoonful of jam on a chilled plate and allow it to cool briefly. Gently push the jam with your finger. If it wrinkles slightly and holds its shape, it has reached a soft set. If it remains runny, cook a little longer and test again. The jam will continue to thicken as it cools. - Finish & store
Remove the saucepan from the heat and stir in the vanilla extract. Carefully ladle the hot jam into clean, heat-safe jars, leaving room at the top for expansion if freezing. Allow to cool briefly, then refrigerate promptly. Keep refrigerated and use within approximately 2–3 weeks, or freeze for longer storage. This recipe is intended for refrigerator or freezer storage, not shelf-stable canning.
From the Table
Mossberries have a flavor that’s difficult to compare to anything else. They’re tart, certainly, but there’s an earthiness to them, too. They’re not particularly sweet, and that’s part of what I like about them.
I’ve made this jam more than once, using berries I’ve gathered myself. One year, I mixed the mossberries with an assortment of other berries. This year, I used strawberries, which turned out to be a lovely combination. Their sweetness softened the sharpness of the mossberries without overwhelming their distinctive flavor.
I also wanted something that felt like autumn, so I added cinnamon, cardamom, and a little nutmeg, finishing with vanilla to round everything out. The spices bring warmth without turning the jam into something that tastes more like a holiday candle than fruit.
There’s a particular satisfaction in making something from berries you’ve gathered yourself. Picking them is only part of the experience. Later comes the washing, sorting, tasting, and deciding what to do with the harvest. Not everything needs to become a large project. Sometimes a couple of little jars of jam are enough.
Field Notes:
Choosing your companion berries. I’ve made this jam with mixed berries and, more recently, with strawberries. Both worked well. Strawberries soften the tartness without competing too much with the earthy mossberry flavor. Raspberries, blueberries, and cloudberries are other possibilities, or you can use mossberries exclusively for a sharper preserve.
Fresh or frozen? Both work. If using frozen berries, thaw them before measuring and include the juices in the saucepan.
A softer set is fine. This jam doesn’t need to be especially firm. A slightly looser consistency makes it wonderful spooned over yogurt, spread on warm bread, or swirled into porridge.
Mind the pectin. Pectin products vary in their requirements for sugar, acidity, and cooking time. The small amount in this recipe may produce a softer set, so consult your particular pectin’s instructions.
Keep the spices subtle. Cinnamon and cardamom complement the earthy, tart character of mossberries, but too much can overwhelm them. Nutmeg adds a little warmth, and vanilla rounds out the finished flavor.
Storage matters. This is a refrigerator or freezer jam, not a tested shelf-stable preserve. Keep refrigerated for approximately 2–3 weeks, or freeze for longer storage. Use clean utensils when serving.
Beyond toast. Try it with cream cheese, spooned over vanilla ice cream, paired with soft cheese, or tucked into thumbprint cookies.
