Autumn olive jam is a delightful preserve made from the small, tart berries of the autumn olive shrub. With its unique balance of sweet and tangy flavors, this jam captures the essence of fall and turns a wild foraged fruit into a versatile spread. It’s perfect for those looking to try something different while making good use of nature’s bounty.
Ingredients
- 4 cups autumn olive berries, rinsed and stems removed
- 3 cups granulated sugar
- 1/4 cup fresh lemon juice (about 2 lemons)
- 1/2 cup water
- 1 packet (1.75 oz) fruit pectin (powdered)
- Optional: 1/2 teaspoon ground cinnamon or vanilla extract for added flavor
Instructions
- Prepare the berries: Rinse the autumn olive berries thoroughly under cold water. Remove any stems or leaves. Because autumn olives have small seeds, you can either cook them whole or crush and strain to reduce seed presence, depending on your texture preference.
- Cook the fruit: In a large saucepan, combine the autumn olive berries, water, and lemon juice. Bring to a simmer over medium heat, stirring occasionally. Allow the berries to soften and release their juices, about 10 minutes.
- Add sugar and pectin: Gradually stir in the granulated sugar. In a small bowl, mix the fruit pectin with 1/4 cup of sugar (taken from the 3 cups) to prevent clumping, then add it to the pot. Stir constantly to dissolve the pectin fully.
- Boil to set: Increase heat to high and bring the mixture to a full rolling boil that cannot be stirred down. Boil hard for 1 minute, stirring constantly to prevent sticking or burning.
- Test for gel consistency: Remove the pot from heat. To check if the jam is set, place a small spoonful on a chilled plate and tilt it. If it wrinkles and holds shape after a minute, it’s ready. If not, return the pot to boil for another 30 seconds and test again.
- Add optional flavors: If desired, stir in ground cinnamon or a teaspoon of vanilla extract after boiling and before bottling to enhance the jam’s flavor.
- Jar the jam: Sterilize your jars and lids by boiling them in water for 10 minutes. Carefully ladle the hot jam into the jars, leaving about 1/4 inch headspace. Wipe rims clean, seal with lids, and process in a boiling water bath for 10 minutes to ensure preservation.
- Cool and store: Remove jars from the water bath and let them cool undisturbed for 12-24 hours. Check seals before storing in a cool, dark place. Refrigerate after opening.
Tips
- Seed removal: Autumn olives have small, hard seeds that some find unpleasant. To reduce seeds, crush the cooked mixture through a fine mesh sieve or food mill before adding sugar and pectin.
- Adjust sweetness: Autumn olive berries are naturally tart. Adjust sugar quantity to taste, but remember sugar helps the jam set and preserves it. Using less sugar may require alternative pectin or longer cooking.
- Storage safety: Always sterilize jars and properly seal to prevent spoilage. If unsure about the seal, refrigerate and consume within 3 weeks.
- Substitutions: If fruit pectin is unavailable, you can use powdered gelatin or agar-agar, but results will differ. Follow package instructions carefully for best texture.
Serving Suggestions
Autumn olive jam’s vibrant sweet-tart flavor pairs wonderfully with toasted breads, biscuits, or scones. It also complements creamy cheeses like goat cheese, brie, or cream cheese, making it a perfect addition to a cheese board. For a twist, swirl it into yogurt or oatmeal, or use it as a glaze for roasted meats such as pork or chicken to add a fruity accent.
Variations
To customize your autumn olive jam, consider mixing in other fruits such as apples, pears, or cranberries to balance the tartness and add complexity. Adding warm spices like cinnamon, nutmeg, or cloves can enhance the fall flavor profile. For a fresh herbal note, stir in chopped fresh rosemary or thyme after cooking. You can also experiment with honey or maple syrup as partial sweeteners instead of sugar, but this may affect setting time.
Storage and Reheating
Properly canned autumn olive jam can be stored unopened in a cool, dark pantry for up to 12 months. After opening, keep refrigerated and consume within 3 to 4 weeks. Always use a clean spoon to avoid contamination. If the jam thickens after refrigeration, gently warm it in a small saucepan over low heat, stirring occasionally until it returns to spreadable consistency. Avoid boiling once opened, as this can degrade flavor and texture.
Frequently Asked Questions
Can I use frozen autumn olive berries to make jam?
Yes, frozen berries can be used and often result in more juice release. Thaw them completely and drain excess liquid before cooking. You may need to adjust the water added in the recipe accordingly.
Are autumn olive berries safe to eat raw?
Yes, autumn olive berries are edible raw and have a tart, somewhat sweet flavor. However, they contain many tiny seeds, which some people find unpleasant. Cooking them into jam softens the seeds and mellows the flavor.
Why did my jam not set properly?
Common causes include insufficient pectin, incorrect sugar ratio, or not boiling the mixture long enough. Make sure to follow pectin package instructions, use fresh pectin, and reach a full rolling boil for at least 1 minute.
Can I make this jam without added pectin?
It’s possible but challenging since autumn olives are low in natural pectin. Without added pectin, you’ll need to cook the jam longer to reduce liquid and concentrate natural pectin, which can alter flavor and texture. Alternatively, mix with higher-pectin fruits like apples or citrus peel.
How do I know when the jars are sealed properly?
After cooling, press the center of each lid. If it doesn’t pop back, the jar is sealed. You can also gently lift the jar by the lid—if it stays firmly attached, the seal is good. If a seal fails, refrigerate and use the jam within a few weeks.
Can I add spices or other flavorings to the jam?
Absolutely. Adding warm spices like cinnamon or vanilla after boiling can enhance the flavor. Fresh herbs can be added after cooking but use sparingly to avoid overpowering the natural berry taste.
Autumn olive jam is a rewarding way to use a wild fruit that’s often overlooked. With its bright flavor and easy preparation, it’s a great introduction to foraged preserves or a seasonal treat to enjoy throughout the year.
