Damson Jam

Learn how to make the ultimate Damson Jam with this easy-to-follow guide that ensures a rich, tart, and perfectly set preserve every single time.

There is something undeniably nostalgic about a jar of Damson jam. As the seasons shift and the air turns crisp, the arrival of these small, dark purple fruits signals the start of the preserving season. Damsons are a subspecies of plum, known for their vibrant tartness and high pectin content, making them the gold standard for jam making. Unlike standard plums, the Damson possesses a deep, complex flavor profile that transforms into a brilliant crimson spread when simmered with sugar.

Making your own preserves at home is a rewarding craft that connects you to generations of kitchen wisdom. While the process might seem intimidating to beginners, it is actually quite straightforward once you understand the science of the “set.” Because the Damson is naturally rich in pectin, you won’t need to rely on store-bought thickening agents. All you need is the fruit, some sugar, a bit of patience, and a few glass jars to capture the essence of late summer for the months ahead.

If you are looking for more fruit-inspired inspiration, you might also enjoy exploring other fruit-based desserts like raspberry cheesecake, which shares that signature balance of tart and sweet. But for now, let’s focus on the star of the show: the mighty Damson.

Why This Damson Jam Recipe Works

This recipe is a favorite among home cooks because it respects the natural integrity of the fruit. The Damson is a “clingson” fruit, meaning the stone doesn’t easily pop out when raw. This recipe uses a traditional method where the fruit is cooked whole first, allowing the stones to rise to the surface where they can be easily skimmed off. This saves you hours of tedious pitting before you even start cooking.

Furthermore, the ratio of fruit to sugar is carefully balanced. We use a 1:1 ratio by weight, which is the traditional standard for long-term preservation. This high sugar content doesn’t just provide sweetness; it acts as the preservative and works with the natural acid in the Damson to create a firm, gel-like consistency that spreads beautifully on toast or scones.

Ingredients

To create the perfect Damson preserve, you only need a handful of high-quality ingredients. Simple is always better when dealing with such flavorful fruit.

• Damsons (1kg / 2.2 lbs): Look for fruit that is ripe but still firm. Avoid any that are bruised or overly mushy.
• Granulated Sugar (1kg / 2.2 lbs): Standard white granulated sugar works best for clarity and set.
• Water (250ml / 1 cup): This helps soften the skins of the Damson before the sugar is added.
• Lemon Juice (1 tablespoon): Optional, but the extra acid helps ensure a reliable set if your fruit is very ripe.
• A knob of butter: This is a secret tip to help disperse the foam (scum) that forms on top of the boiling jam.

Equipment

Before you begin, ensure you have the following tools ready. Jam making moves quickly once the “rolling boil” starts, so preparation is key.

• A large heavy-bottomed pot: Ideally a maslin pan or a large Dutch oven. The Damson mixture will bubble up significantly, so the pot should be only half full.
• Sterilized glass jars: Ensure they have airtight lids (Lacquered lids are best for high-acid fruits).
• A long-handled wooden spoon: For stirring without getting burned by splashes.
• A small saucer: Kept in the freezer for the “wrinkle test.”
• A slotted spoon: Specifically for removing the Damson stones as they float to the top.
• A jam funnel: To make jarring the hot liquid much cleaner and safer.

1. Prepare the Fruit: Wash the fruit thoroughly in cold water. Remove any stems or leaves. Place the whole Damson fruits into your large pot along with the water.
2. Soften the Skins: Simmer the fruit gently over medium heat for about 15-20 minutes. You want the skins to burst and the fruit to become a pulpy mass. This is crucial because if you add sugar too early, the skins will toughen and never soften.
3. Remove the Stones: As the fruit breaks down, the stones will begin to release. Use your slotted spoon to fish them out. Don’t worry if you miss a few; they will continue to pop up as the mixture boils later.
4. Add the Sugar: Turn the heat to low and pour in all the sugar. Stir continuously until the sugar has completely dissolved. You should not feel any gritty crystals on the bottom of the pan.
5. The Rolling Boil: Once the sugar is dissolved, turn the heat up to high. Bring the Damson mixture to a “rolling boil”—a boil that cannot be stirred down. Let it boil vigorously for 10-15 minutes.
6. The Wrinkle Test: Remove the pan from the heat. Take your cold saucer from the freezer and place a small teaspoon of jam on it. Wait 30 seconds, then push the jam with your finger. If it wrinkles, it has reached the setting point. If not, boil for another 2 minutes and test again.
7. Jar and Seal: Stir in the knob of butter to clear any foam. Let the jam sit for 10 minutes (this prevents the fruit pieces from sinking to the bottom of the jars). Pour into sterilized jars using a funnel, leaving about a 1/4 inch of headspace, and seal immediately.

To Incorporate With

This Damson preserve is incredibly versatile. While it is classic on a slice of buttered sourdough, its tartness makes it an excellent accompaniment to savory dishes as well. Try it as a glaze for roast duck or lamb, where the acidity cuts through the fat perfectly.

For a sweet treat, use it as a filling for Victoria sponge cakes or swirl it into Greek yogurt for a quick breakfast. It also makes a fantastic topping for fluffy christmas pancakes, providing a sophisticated alternative to maple syrup. If you are feeling creative, you can even find more serving ideas on Pinterest.

Varieties / Substitutions

If you cannot find a Damson, the closest substitute is the Italian Prune Plum or the Bullace. These fruits share the same astringent quality that mellows into sweetness when cooked.

• Spiced Damson: Add a cinnamon stick and two star anise during the softening stage for a warm, autumnal flavor.
• Damson and Gin: Stir in 2 tablespoons of high-quality gin right before jarring for a “sloey” botanical kick.
• Reduced Sugar: While 1:1 is standard, you can reduce sugar to 750g per 1kg of fruit, but note that the shelf life will be shorter and the set may be softer.

Tips for Success

Getting the perfect set with a Damson can sometimes be tricky for beginners. Here are the professional secrets to ensure success every time:

• Don’t overcook: If you boil the jam for too long, the sugar will caramelize, and the bright Damson flavor will turn into a burnt, sticky mess. Always start testing for a set at the 10-minute mark.
• Stone Management: Count your damsons before you put them in. If you know you put in 50 fruits, you know you need to find 50 stones! (Though most people just accept a few “lucky” stones in the jars).
• Sterilization is Key: To ensure your jam lasts up to a year, your jars must be bone dry and hot when the jam goes in. You can sterilize them in a 100°C (212°F) oven for 15 minutes.
• Surface Scum: The white foam that appears is just air bubbles and impurities. It’s harmless, but a knob of butter at the end breaks the surface tension and makes it disappear instantly.

10 FAQ

1. What does Damson jam taste like? It is significantly more tart and “plum-forward” than standard plum jam, with a rich, tannic skin flavor that balances the sugar.
2. Do I have to peel damsons? No, the skins contain the pectin and the color. They soften beautifully during the initial simmer.
3. Why is my jam runny? It likely hasn’t reached the setting point (104°C / 220°F). Re-boil it with a splash of lemon juice.
4. Can I use frozen damsons? Absolutely! Defrost them slightly before starting the simmering process.
5. How long does it last? Properly sealed and stored in a cool, dark place, it will last for 12 months. Once opened, keep it in the fridge.
6. Is Damson jam the same as plum jam? Not quite. While related, the Damson has a higher acid and pectin content, leading to a firmer set and sharper taste.
7. Can I make this in a bread machine? While possible, the stone removal process makes the stovetop method much more practical.
8. Why did my stones sink? Stones don’t sink; they usually float! If fruit pieces sink, it’s because the jam was jarred while too hot and thin.
9. Can I use honey instead of sugar? Honey changes the flavor significantly and doesn’t preserve as effectively as granulated sugar.
10. Where can I find more recipes? You can Search for more Damson recipes on Food.com.
