The MOST Delicious Rhubarb Jam Recipe – With Fresh or Frozen Rhubarb

This is my ABSOLUTE FAVORITE and the MOST DELICIOUS Rhubarb Jam Recipe that I'm happy to share with you today! Fresh or frozen, I have the details on how to handle both.
If using frozen rhubarb, DO NOT drain the liquid.  You will use this PLUS the water called for to cook your rhubarb.

I have made it no secret that I LOVE rhubarb.  In case you missed them, I’ve shared about growing rhubarb and my recipe for rhubarb bars, strawberry rhubarb lemonade slush, and rhubarb raspberry ice cream sauce.  But today it’s all about my rhubarb jam recipe.

The other day I tackled my frozen rhubarb and made a couple of batches of my favorite rhubarb jam.

I’m telling you, this jam has the perfect balance of tart/sweet and the cinnamon adds such a lovely spice!

I think rhubarb strawberry jam is the most popular rhubarb jam.  But sometimes you’re just out of strawberries and have a craving for some rhubarb.  Truth be told, I prefer this jam to rhubarb strawberry.

Before we get into the recipe, let me mention a few things.

Fresh or Frozen for Rhubarb Jam Recipe?

You can use either fresh or frozen rhubarb for this jam.  Below is a comparison of both.

FRESH – 1 small to medium stalk of rhubarb will be cut up to around 1/2 of a cup for fresh rhubarb.  For this recipe, you will need about 10 to 12 stalks or enough to get about 6 cups of unprepared rhubarb, depending on the size of your rhubarb stalks.

FROZEN – 6 cups of diced and frozen rhubarb are usually sufficient for this recipe.  Place your frozen rhubarb in a bowl and let it thaw completely.  The rhubarb will seem to shrink down but you’ll remeasure your rhubarb after cooking it so you have the correct amount for your jam.  Do NOT drain the juice after thawing; you will use that to prepare your rhubarb.

Storage

This recipe produces 6 half-pint jars of jam.  You can freeze this jam in freezer-safe containers/jars or process it in a water bath canner for long-term shelf storage.

By the way – it makes a GREAT gift for fellow rhubarb lovers!

Acidity Question

Rhubarb is a vegetable and it is actually acidic.  Because of this, an added acid (lemon juice, vitamin c., etc.) is not required.  You may find that your storebought pectin has ascorbic acid in it.

This added acid is not a concern when you make your jam.  I’ve had great results using pectin with ascorbic acid or without.  However, I do not recommend you add any acid to your jam as it isn’t necessary.

Now let’s get to making this the most delicious Rhubarb Jam recipe you’ll ever enjoy!

    • Hi Trish, you’ll want to keep the juice. As you prep your rhubarb, you will boil it in juice/water and then remeasure your rhubarb for use in the jam.
