Blueberry Marmalade: Use Your Summer Harvest

Cary, NC — This recipe is one of the easiest jam recipes I have ever made. For the last three weeks, the Cary Downtown Farmers Market has had a stand with the most amazing blueberries! The first week I bought one container. The next week I bought two, swearing I would make jam. We ate them all. This week, I finally got out my canning jars and whipped up a batch of Blueberry Marmalade. And it was so easy.

Since it is a marmalade, that means you have to add citrus. And lucky for me, I usually have Cara Cara Oranges in the fridge at all times along with a rogue lemon or lime. All are required plus some granulated sugar and some red pepper flakes.

Simple ingredients are always the best. Three types of citrus plus the blueberries, sugar and water. Red pepper flakes give this recipe a kick, too.

Assemble Tools Before Starting

Before getting start, make sure you’ve got these tools on hand:

  • A large pot to boil the jars
  • A 2-quart saucepan for the jam
  • 6 1/2 pint glass ball jars, the kind with a metal band for the rim and a separate metal lid.
  • Metal tongs to pull the jars out.
  • Ladle to pour the jam into the jars
  • Paper towels or clean rags to clean off the lids
  • Cutting board and paring knife
  • Juicer
  • Small bowl

Prep is a Breeze

Now that you have the tools assembled, clear the work surface next to your stove so that all of this can happen in close proximity to the cooking area.

To make this jam/ marmalade, you will need at least 6 glass half-pint jars with lids, and they should be put in a boiling water bath to sterilize them while the jam is being made. This step is critical or you will have a jam that is not sanitary and may actually make you sick. Safety first!

To do this, I find the biggest pasta or soup pot that I own, take the lids off all the jars and place them neatly in the pot. Then I add all the bands and lids in with the jars, and fill the pot to above the level of the jars, making sure everything is underwater. Place the pot on a burner, turn the heat to high, and start boiling for at least 10 minutes. Keep the heat on well into the jam-cooking process because the jam must be added to HOT jars. Then, it gets sealed up and boiled for at least another 10 minutes.

A good rolling boil is key to your jam setting up properly.

To Make the Jam

Here are the ingredients to make this marmalade:

  • 2 cups of blueberries washed and de-stemmed
  • 1 orange
  • 1 lemon
  • 1 lime
  • 2 cups water
  • 1/2 teaspoon red pepper flakes
  • 2 cups granulated sugar
  1. With the paring knife, cut the rind off of all the citrus fruit and slice into thin strips. Slice each fruit in half and squeeze the juice of each into a bowl, and include the pulp. Set aside.
  2. In the 2- quart saucepan, bring the rind strips, water, and red pepper flakes to a boil. Cover, reduce heat to a simmer for at least 25 minutes, or until the rinds are tender.
  3. Add the blueberries, sugar, citrus pulp and juice to the saucepan. Bring to a full rolling boil. Continue boiling, uncovered for at least 15 minutes, stirring frequently, until a gel forms. Remove from heat, and skim off any foam.
  4. With a ladle, pour the jam into the hot sterilized jars. Leave 1/4″ from the top. Wipe off the excess around the rims. Cover with the metal lids and screw on the bands tightly.

After the jam is sealed in your jars, they must undergo a 10-minute processing in boiling water to set properly and be sterilized.

Put the filled jars back into the boiling water for at least 10 minutes to process them.

Note that frozen blueberries can be used for this recipe if you are making this in another season.

Right now blueberries are in season in North Carolina and they are usually available fresh in our area through mid-July. A great place where you can pick your own is Herndon Hills Farm in Durham (near Southpoint Mall). But you have to go early as they sell out fast.

    I am looking forward to trying this recipe today! I have two questions though. Do you use the rind or do you zest the citrus? What do you do with the sterilized jars between the time that they have boiled to when you add the blueberry mixture? Do you take them out of the water bath and invert them on a clean towel until you fill them? Or what?
    Thank you!
