Raspberry Jam

As an Amazon Associate I earn from qualifying purchases.

I can’t tell you how many summer mornings I’ve spent in our food forests with my kids, picking fresh raspberries and trying (sometimes failing!) to get more in our baskets than in our mouths. Those berries that do make it inside? They wait in the freezer until we’re ready to transform them into the most incredible homemade jam.

It’s become such a favorite in our household that the kids now guard our jam supplies carefully, making sure we always have enough to last until the next berry season.

This homemade raspberry jam recipe is dedicated to guarding our supply .

Raspberry jam in jars with fresh raspberries.

Tips


  • ALWAYS prepare an extra quarter pint jar when Iโ€™m making jam. Just in case I have a smidge less than I expected I have a jar thatโ€™s ready to go when I canโ€™t fill a half pint jar.
  • We can eliminate the jar sterilization step in this recipe by ensuring the jam jars are in the water bath canner for at least 10 minutes, so thatโ€™s my timings look a little different than other recipes.
  • Finger-tight is such a vague term, hereโ€™s how I tighten my jars: screw the bands on until the jar starts to turn on the counter, then back off about a 1/8th of a turn.
  • If youโ€™re using frozen berries like me, allow them to thaw at room temperature before crushing, itโ€™s much easier than smashing frozen berries! Make sure you mash the berries well โ€“ this is the key to smooth jams.
  • Raspberry juice stains! So donโ€™t wear white, or use a wooden spoon that may never recover from the dye!

Canning Safety

Sterilizing Jars:

Everyone and their dog has their own way of cleaning jars, but make sure that you do it. National Center For Food Preservation has CLEAR GUIDELINES about sterilizing jars. The TL;DR is that if youโ€™re processing for at least 10 minutes, sterilization is not required โ€“ this is why I do not sterilize my jam jars (and process for at least 10 minutes!)

Processing Time:

When water bath canning, you must know your elevation due to the different temperatures at which water boils based on elevation and the length of time food must be held at a certain temperature before it is considered pasteurized. A higher altitude equals lower boiling temperature and longer processing time.

Key Ingredients

Raspberries: Always choose high quality, ripe berries. Pick through them to remove any molded, bruised, or damaged fruit, then wash well before use. You can use fresh or frozen berries for this recipe!

Sugar: Granulated sugar imparts sweetness without impacting flavor, so I prefer it for jam recipes where I want my fruit flavor to shine through. It also dissolves easily in the heated jam and helps to preserve the flavor, color, and texture of the jam while also making it shelf-stable!

Ingredients required for this recipe.

How To Make Raspberry Jam

Prepare Your Canning Jars:

  1. This recipe makes 8 half pint (250 ml) jars and does not require sterilization due to the processing time. Prepare your jars, flats, and rings by washing in hot soapy water and rinsing well before setting aside on a clean kitchen towel until youโ€™re ready to use them.
  2. Fill a water bath canner, and set to boil over medium high heat.

Prepare The Berries:

  1. Gather approximately 3 pounds (12 or so cups) of raspberries.
  2. If using frozen berries, thaw them first. Place fresh or thawed berries in a single layer in a large bowl. Mash well with a potato masher. Repeat; adding layers and mashing until all berries are crushed.
  3. Measure berries and their juice, ensuring you have 5 cups of crushed berries.

Make The Jam:

  1. Place 5 cups of prepared raspberries in a large, heavy bottomed saucepan. Stir in one 57g package of powdered pectin, and 1/2 teaspoon of butter, optional โ€“ but can help reduce foaming .
  2. Bring the berry mixture to a full rolling boil over medium-high heat, then stir in 7 cups of granulated sugar.
  3. Stir the jam mixture constantly while it comes back to a full rolling boil โ€“ this is a boil you cannot stir down. Boil for 1 minute.
  4. Remove the sauce pan from heat, scoop off any foam if necessary.

Process The Jam:

  1. Ladle hot jam into prepared canning jars leaving 1/4 inch headspace. Wipe jar rims, center a new snap lid on each jar, and tighten bands finger tight.
  2. Transfer filled jars to the prepared boiling water bath canner using a jar lifter, ensure the jars are covered by 1-2 inches of water, cover the canner and return to a full boil.
  3. Once the water bath returns to a boil, begin to process for 10 minutes (at 0- 1,000 feet above sea level, see section above for canning at other altitudes).
  4. When processing is complete, turn off the heat, remove the lid from the water bath canner, and rest for 5 minutes before removing the hot jars and transferring them to a heat-proof surface to cool untouched for 24 hours.
  5. After 24 hours, remove the screw bands, wipe down the jars, and place them in long-term storage location.

Label Your Jam:

I love to label my handcrafted goodies. I used myย Munbyn thermal printerย andย 2″ round labelsย for this project. I created the labels in Canva.

SERVING SUGGESTIONS

Here are some of my favorite ways to enjoy my homemade jam!

Batch + Storage

Batch:

This recipe makes between 8-9 half pints of delicious homemade raspberry jam. Itโ€™s a great idea to always prep 1 jar thatโ€™s a size smaller than the jars youโ€™re using to deal with leftovers!

For example, I am using half pint (250 ml) jars for this jam recipe, but I have also prepared a quarter pint (125ml) jar in case there isnโ€™t quite enough jam to fill another half pint jar!

I donโ€™t recommend doubling jam recipes, I find things can go wonky, I recommend just making concurrent batches of jams.

Storage:

Properly water-bathed jam can be kept in a cool, dark place, for a shelf life of up to 12 months. While the lids may seal for longer, flavor, texture, and color can change in an undesirable way. Even properly processed and stored foods can lose their quality over time, so itโ€™s important to cycle the stock of your canned goods. Degradation occurs more quickly in temperatures above 70f or 21c.

Pectin Jam vs Pectin Free Jam

When making berry jams, I usually opt for the versions with pectin.

Pectin free jams require twice as much fruit and usually only a cup or so less sugar for the same amount of jam. This means youโ€™re concentrating the flavor and sweetness in the jam and while that sounds great it can be cloying, or excessively sweet and cause the loss of the natural tartness and flavor profile of the berry.

The other downside is that pectin free jams require more cooking to render out the liquid from the berries โ€“ they are cooked down by pretty much half. This can result in a less fresh, more โ€œcookedโ€ flavor that lacks the depth and nuance of fresh berries.
