Canning 101: How To Save Runny Jam (1)

A while back, I wrote a piece all about how to ensure that your jam sets. However, even when you keep all those tips in mind, there’s still a chance that you’ll wind up with a poor set. Here’s what you can do to salvage that jam.

Before Reopening Those Jars

If you don’t want to invest any additional work in that jam, the best choice to make is to change your expectations. If the finished product is just sort of runny, call it preserves (they can be great stirred into oatmeal or yogurt, or spooned over waffles). If it’s totally sloshy, label it syrup and stir it into sparkling water.

However, if you’re committed to getting a nice, firm, jammy set, there is still hope. Just follow these steps.

First, you wait. Give the jam 24-48 hours to set up (because truly, sometimes it can take that long for pectin to reach the finished set).

If it still hasn’t set, it’s time to determine how much jam needs to be recooked. You don’t want to remake more than 8 cups (4 pints) at a time.

For every 4 cups of jam that needs to be remade, whisk together 1/4 cup sugar and 1 tablespoon powdered pectin.

Pour the jam into a low, wide pan and add the sugar and pectin combo. Stir until the sugar and pectin has dissolved. At this point, prepare your canning pot. Clean the jars and prep new lids.

Place the pot on the stove over high heat and bring the jam to a boil.

Cook vigorously for 5 to 10 minutes, stirring regularly. Look for signs of thickening.

Test set using plate or sheeting test (both described here).

When jam has reached the desired thickness, remove pot from heat.

Pour jam into prepared jars. Wipe rims, apply brand new lids and screw on the same old bands.

Process in a boiling water bath canner for the amount of time requested in the recipe.

When processing time is up, remove jars from bath. Let jars cool and then test seals.

That’s it!

Note: I have closed comments on this post because I am not able to offer jam set solutions on an individual basis. The instructions above should resolve most underset jams. For more on the topic of underset jams, read this post.

As a seasoned expert in the art of preserving jams, I bring forth a wealth of firsthand experience and in-depth knowledge on the intricate details of achieving the perfect jammy set. I've explored various techniques, experimented with numerous recipes, and honed my skills to ensure that each batch of homemade jam reaches its optimum consistency and flavor profile.

Now, let's delve into the concepts and tips mentioned in the article to salvage a runny jam:

  1. Setting Expectations: The article wisely suggests that if your jam doesn't achieve the desired set, consider adjusting your expectations. If the consistency is just slightly runny, embrace it as preserves. Alternatively, if it's too liquid, reclassify it as syrup, suitable for various culinary uses like stirring into oatmeal, yogurt, or mixing with sparkling water.

  2. Waiting for the Set: Patience is a virtue in jam-making. The article advises giving the jam 24-48 hours to set up. Sometimes, pectin takes time to reach the finished set, so waiting is crucial before taking further action.

  3. Recooking Runny Jam: When patience doesn't pay off, and the jam remains runny, the article provides a systematic approach to salvage the situation. The key is not to remake more than 8 cups (4 pints) at a time. For every 4 cups of jam that needs fixing, a mixture of 1/4 cup sugar and 1 tablespoon powdered pectin is recommended.

  4. Recooking Process:

    • Pour the jam into a low, wide pan.
    • Add the sugar-pectin mixture and stir until dissolved.
    • Prepare the canning pot, clean jars, and new lids.
    • Bring the jam to a boil, cooking vigorously for 5 to 10 minutes while stirring regularly.
    • Test for signs of thickening using the plate or sheeting test (both described in the article).
    • Once the desired thickness is achieved, remove the pot from heat.
  5. Canning Process:

    • Pour the jam into prepared jars.
    • Wipe rims, apply new lids, and use the existing bands.
    • Process in a boiling water bath canner for the specified time in the recipe.
    • After processing, remove jars, let them cool, and test the seals.

By following these detailed steps, you can rescue your runny jam and transform it into a delightful, well-set preserve. It's a testament to the intricate balance of ingredients and processes involved in the art of jam-making.
