I do love blueberries on their own, but sometimes you just need a little something extra to really bring out the flavour of a berry. If you are looking for a jam that really kicks it up a notch, you’ve come to the right place. Adding the juice and zest of a lime or two really enhances the flavour of the blueberries and makes a delicious jam. This recipe is from the Ball Complete Book of Home Preserving. The only change that I make is to use a lower sugar pectin and less sugar, and two limes rather than one, but here it’s written as in Ball.

Ingredients:
4.5 cups crushed blueberries
5 cups sugar
Zest and juice of 1-2 large limes
1 package of regular pectin (or use low sugar pectin and adjust sugar accordingly)

Here’s what we did:

Prepare the canner, jars and lids. This yields around 6 half pints unless you reduce the sugar.

In a stainless steel pot, combine the crushed berries, lime juice, lime zest, and pectin. Mix well to combine all the ingredients.

Bring the jam to a full rolling boil over high heat, stirring constantly.

Add the sugar all at once when the boil is reached, and return to a boil. Boil hard for 1 minute, then remove from heat and skim off any foam.

Fill the hot jars leaving a 1/4 inch head space. Wipe rims, apply lids, and tighten the bands finger tip tight.

Process the jars in a boiling water bath canner, covered by at least 1-2 inches of water for 10 minutes, starting the time when the water reaches a full rolling boil. After the 10 minutes, turn off the heat, remove the canner lid, wait 5 minutes and remove the jars to a hot pad or towel. Cool the jars 12-24 hours, remove bands, check seals, wipe clean, label and store.
