Blueberry bourbon jam is a luscious, richly flavored spread that blends the natural sweetness of ripe blueberries with the warm, smoky notes of bourbon. This jam works beautifully as a versatile condiment, perfect for breakfast toast, cheese boards, or even as a glaze for meats. Making it at home allows you to control the balance of sweetness and alcohol, resulting in a uniquely delicious preserve that’s both boozy and comforting.
Ingredients
- 4 cups fresh or frozen blueberries (about 600g)
- 1 ½ cups granulated sugar (300g)
- 1 tablespoon lemon juice (freshly squeezed)
- 1 teaspoon lemon zest
- ¼ cup bourbon whiskey (60ml)
- 1 packet (1.75 oz) fruit pectin (powdered, such as Sure-Jell)
- ¼ teaspoon salt
Instructions
- Prepare jars and equipment: Sterilize 2-3 half-pint (8 oz) jam jars and lids by boiling them in water for 10 minutes. Keep warm until ready to fill.
- Cook the blueberries: In a large heavy-bottomed saucepan, combine the blueberries, lemon juice, lemon zest, and salt. Cook over medium heat, stirring occasionally, until the berries soften and release their juices, about 5-7 minutes.
- Add sugar and pectin: Stir in the granulated sugar and sprinkle the fruit pectin evenly over the mixture. Stir constantly to dissolve the sugar and pectin.
- Bring to a boil: Increase heat and bring the mixture to a full rolling boil (one that doesn’t stop bubbling when stirred). Boil hard for 1 minute, stirring constantly to prevent scorching.
- Remove from heat and add bourbon: Take the pan off the heat and stir in the bourbon thoroughly. The alcohol will mellow slightly but still infuse the jam with flavor.
- Skim foam and jar the jam: If foam forms on the surface, skim it off with a spoon. Carefully ladle the hot jam into the prepared jars, leaving about ¼ inch headspace.
- Seal jars: Wipe rims clean, place lids on jars, and screw on bands until fingertip tight.
- Process jars (optional for shelf stability): For longer storage and shelf stability, process jars in a boiling water bath for 10 minutes. Otherwise, allow jars to cool at room temperature, then refrigerate and consume within 3 weeks.
- Cool and store: Let jars cool completely on a towel or rack overnight. Check seals (lids should not flex when pressed). Store sealed jars in a cool, dark place or refrigerate.
Tips
- Substitution: If you prefer a less boozy jam, reduce bourbon to 2 tablespoons or substitute with vanilla extract for flavor without alcohol.
- Fruit pectin: Use powdered pectin designed for regular sugar jams. Low-sugar pectin requires a different method and may alter texture.
- Prevent burning: Stir constantly once sugar is added to avoid scorching on the bottom of the pan.
- Storage: Unprocessed jam must be refrigerated and eaten within 3 weeks. Properly canned jam can last up to 1 year unopened.
Serving Suggestions
This blueberry bourbon jam pairs wonderfully with warm buttered toast or freshly baked biscuits for a decadent breakfast. It’s also excellent spooned over vanilla ice cream or swirled into Greek yogurt for a boozy twist on dessert. For savory uses, try it as a glaze on roasted pork chops or mixed into a cheese platter alongside sharp cheddar or creamy brie. The jam’s rich flavor complements smoked meats and charcuterie beautifully, making it a great addition to appetizers and sandwiches.
Variations
To customize this jam, you can experiment with different fruits or spices. Try substituting half the blueberries with blackberries or raspberries for a more complex berry blend. Adding a pinch of cinnamon or ground ginger during cooking introduces warm spice notes that complement the bourbon. For a citrusy twist, increase lemon zest or add a splash of orange juice. If you want a less sweet jam, reduce sugar by ¼ cup but keep in mind it may affect gel strength.
Storage and Reheating
Store unopened, properly processed jars in a cool, dark pantry for up to 12 months. After opening, keep the jam refrigerated and consume within 3 weeks for best quality. If refrigerated jam thickens too much, gently warm it in a small saucepan over low heat, stirring until it loosens to your desired consistency. Avoid microwaving directly in the jar to prevent uneven heating or cracking glass. Always use a clean spoon to avoid contamination and extend shelf life.
Frequently Asked Questions
Can I use frozen blueberries for this jam?
Yes, frozen blueberries work well and are often preferred out of season. Thaw them slightly before cooking and drain any excess liquid to avoid diluting the jam.
Does the alcohol cook off during jam making?
Because bourbon is added after the boiling step and only stirred in off heat, much of the alcohol remains in the jam, preserving its flavor and boozy character. If you want less alcohol, reduce the amount or add after the jam cools.
How do I know when the jam has set properly?
Use the plate test: chill a small plate in the freezer, then spoon a bit of hot jam onto it. After a minute, push the jam with your finger—if it wrinkles and doesn’t flood back, it’s set. If not, cook a few minutes longer and test again.
Can I can this jam safely without a pressure canner?
Yes, because blueberry jam is high-acid (thanks to lemon juice), it can be safely processed using a boiling water bath. Follow USDA guidelines for water bath canning times and jar sterilization to ensure safety.
What if my jam is too runny?
If your jam doesn’t set after cooling, you can return it to the pot and boil it again for a few minutes, stirring constantly. Adding a small amount of additional pectin can also help, but avoid overcooking which can darken flavor.
Can I make this jam without pectin?
Yes, but the jam will take longer to thicken and may have a looser texture. Cook the berries and sugar for a longer time (up to 30-40 minutes), testing frequently for setting. Note that the jam may be less stable for long-term storage without pectin.
