Ingredients

Preserving Hardware:

  • Large stockpot or canning kettle
  • Jar rack or cake cooling rack (for holding filled jars off the floor of the pot
  • 6 (8-ounce) Mason style preserving jars with lids and bands
  • Wide mouth canning funnel (technically optional, practically indispensable)
  • Canning tongs (specially made for snatching jars in and out of very hot situations
  • Large (8-ounce) ladle
  • Paper towels or dishtowels
  • Magnetized "lid-wand" or magnet tool from hardware store (optional, but how else you gonna get hold of those darned lids)

Jam Hardware:

  • Medium-large saucepan
  • Wooden spoon
  • Hand masher
  • Nutmeg grater (optional)

Jam Software:

  • 2 (12-ounce) bags frozen blueberries
  • One (1 3/4-ounce) packet dry pectin
  • 1/4 teaspoon star anise, ground fine
  • 10 to 20 grinds fresh nutmeg (or 1/4 teaspoon pre-ground)
  • 2 tablespoons lemon juice
  • 5 tablespoons (2 1/2 ounces) cider vinegar
  • 3 cups sugar
  • 1/2 cup water

Directions

For the jam: Place blueberries in saucepan over medium-low heat. Sprinkle with pectin followed by the anise, nutmeg, lemon juice and vinegar. Once liquid starts to gather in bottom of pan, increase the heat to high and bring to a boil. Lower heat slightly and boil gently for five minutes occasionally mashing mixture. Mash in sugar, add the water and return to a boil for 1 minute. You just made jam. Cool, jar, refrigerate and enjoy within 2 weeks. Or, move to the preserving phase.

Preserving the jam: Thoroughly wash all hardware in hot soapy water. Then pile everything (excluding the jar lids) into the pot. Cover with hot water by at least 1-inch and bring to a boil and maintain for 10 full minutes to sterilize. Turn off the heat, wait 5 minutes then add the lids (waiting will insure that the sealing compound does not melt). Leave all hardware in the pot until you're ready to can.

Remove the ladle, tongs, funnel and other tools from the pot, (careful please, it's hot in there) to a clean towel or paper towels. Using the jar tongs, remove and drain the jars, placing them on the towel/paper towel surface. (Avoid rock or metal surfaces which could result in thermal shock and breakage.)

Place the funnel in the first jar (pick it up by the ring, avoiding the sterile interior.) Use the ladle to fill each jar just to the bottom of the funnel, about 1/3-inch from the bottom of the jar threads. This "headspace" is necessary for the jars to seal during processing.

Wipe the jar rims with a moist paper towel, checking for any cracks or irregularities as you go. Use the magnetized device of your choice to position lids on each jar. Screw the rings on finger tight. (Remember, the rings don't seal the jars they only hold the lids in place. Heat will drive out the headspace air, which when cooled will create a vacuum, thus sealing the jars)

Return the jars to the pot being certain that they don't touch the bottom of the pot or each other. (If you don't have a jar rack, try a round cake rack, or metal mesh basket. Even a folded kitchen towel on the pot bottom will do in a pinch.) Add additional water if necessary to cover the jars by at least an inch, and bring to a hard boil over high heat according to the table below. (Be sure not to start your timer until a true boil is reached. The headroom air may bubble out of the jars before a boil is reached. Don't be fooled.)

Processing times: Within 1,000 feet of sea level: 5 minutes 1,000 - 3,000 feet above sea level: 10 minutes 3,001- 6,000 feet above sea level: 15 minutes 6,000 - 8,000 feet above sea level: 20 minutes Above 8,000 feet: wait until you're back down at base camp.

    This IS Jammin!

    Rated: 5 stars out of 5
    Great jam, and easy to make...I went to 5 different stores to find the star anise, because I really wanted to stick to the... recipe, and itwas worth the trouble. (btw, after several stores, including whole foods, I found the star anise at a little hispanic grocery store). I will be making this again, for christmas gift baskets, and I love that I can use frozen berry's. I may even try it with strawberrys...Thanks Alton.. Alyson in Marietta GARead more

    Vinegar & Nutmeg rocks

    Rated: 5 stars out of 5
    Please please please don't be afraid of apple cider vinegar. It's an acid just like lemon juice. The spices combined with... the vinegar make this jam so so so interesting. I did use fresh in-season berries from the farmer's market. When it comes to flavors and food chemistry, though, Alton knows what he is talking about. Please try it!!!Read more

    Great Jam

    Rated: 5 stars out of 5
    I made 3 batches, using less vinegar each time. I didn't use vinegar at all in the last batch, and it was my favorite.

    Good enough for a wedding

    Rated: 5 stars out of 5
    I too was confused about the vinegar so I just used 3 tsp. instead of 5 and upped the lemon juice to 3 tsp and it was... wonderful. So wonderful that my daughter wants to learn to make jam. Thanks AltonRead more

    The best blueberry jam in the world, ever.

    Rated: 5 stars out of 5
    I made a batch two days ago, and opened up the first jar at breakfast this morning. Wow, this stuff is delicious. You will... never, ever taste a better blueberry jam, and it's so easy to make. I'm making another batch today for friends and family. By the way, if you decide to make it, do yourself a favor and get frozen _wild_ blueberries. They're so much more flavorful than cultivated varieties. And don't worry about the vinegar. I used the full amount in my batch, and there's no vinegary taste at all. Just powerful blueberry flavor up front - not overly sweet - with a hint of a tang at the end. Yum.Read more

    Rated: 5 stars out of 5
    This is very fast and tasty. It makes great jam and wounderful sauce. I did cut the sugar and used clear jell. We are... diabetic. It makes a little less, but the flavor is right up there with the best.Read more
