Making Blueberry Jam

101As far as I’m concerned, Blueberry Jam is definitely one of the great tastes of summer.  My kids enjoy it on a peanut butter sandwich or as a decadent topping on pancakes.  It’s also a great reminder of those warmer days when we are in the throes of those Winter months.  Like all jams, it’s easy to make and great to share!

Ingredients

8 cups crushed berries

10 cups sugar

4 Tablespoons lemon juice

2 packages of pectin (57 g /2 oz.)

Yields 14 -250 ml (8.4 oz. or half pint) jars of jam

Note:  Make this jam in two separate batches.

Directions for 7 jars of jam

Fill your canner up with hot water to the height of the jars that you will be using for your jam. It will take a while to get this volume to a boil so you better start now.  If you get ahead of the game, you can always turn it down later.

Fill a medium pot with water and add the seals and screw rings.  Bring this to a gentle bowl.

Sterilize your jars in the oven at 225 degrees fahrenheit  for 10 minutes.  Continue to keep them warm in the oven until they are needed.

Mash the berries up in a large bowl.  If you like your jam to be more “chunky”, then decrease the amount of mashing.

002

Combine mashed berries and pectin in a large pot and bring to a boil over high heat.

Add all the sugar.  I add 1/3 at a time and stir in order to dissolve all the sugar and not have it stick to the bottom.

Note:  Make sure you use a LARGE pot to make this jam.  The volume will really INCREASE when the jam begins to boil.  The last thing you will want is to have this sugary mixture bubble over the pot and catch FIRE on your burner.  Been there and done that!

Once the sugar is dissolved, return to a hard boil for 1 minute.

Remove from heat. Stir and skim for 5 minutes.  This step is crucial in order to get a foam free jam (skimming part) that doesn’t have the fruit rising to the top of the jar (stirring part).

008Pour jam into warm sterilized jars to 1/4″ from rim.

Wipe the lip of the jar with a wet paper towel in order to ensure that no jam is on the rim of the jar.  This could prevent a good seal from happening.  Cover with sterilized lids and tighten the screw rings.

Process in a water bath for 10 minutes. Carefully remove the jars with canning tongs and cool on a rack over night.  Soon you will hear the sound of success as those lids start popping and ensuring a good seal.

025Congratulations!  Try not to eat it all in the next few months.  Save some for the Winter when you will need a few reminders of summer!
