Raspberry Jam

It’s THAT time of year once again… I go and pick fresh berries at a local U-Pick Farm, then come home and “morph” the berries into several different recipes. This Raspberry Jam is the result of my latest berry picking adventure!Raspberry Jam / The Grateful Girl Cooks!
There’s something to be said for picking your own raspberries in the cool of the morning on a gorgeous day. That’s my feeling every single time I pick berries at a local U-Pick Farm.

This time I picked about 14 pounds of Willamette Red Raspberries. Here’s a few of them…

To make the jam, I first washed and pre-heated my jars and lids (lids are in separate bowl).

I crushed the raspberries (using my trusty potato masher), measured the exact amount of raspberries into a large cooking pot, then added one box of powdered pectin, and stirred it in.

I brought the raspberry/pectin mixture to a full rolling boil, then added the sugar quickly, and stirred it all to combine.

I brought the raspberry/pectin/sugar mixture to a full rolling boil, then continued boiling it for exactly 4 minutes, stirring constantly.

After it boiled for 4 minutes, I removed my pan from the heat, and then skimmed off the foam that had accumulated on the top of the jam mixture.

I ladled the HOT jam into my prepared canning jars, using a wide mouth canning funnel.

I added jam up to 1/8 inch headspace from the top of the jar, then followed standard canning instructions for removing the air bubbles from jam.

I adjusted the headspace (if necessary), then wiped the rim of the jar with a wet paper towel to remove any jam debris (so the jar would seal properly).

I used my magnetic canning wand to pick up the hot lids out of the water, and placed one on each jar.

I screwed on the jar rings fingertip tight, then carefully lowered jars into my water bath canner, making sure that the jars were completely covered by at least one inch of water above the tops of the jars.

Raspberry Jam / The Grateful Girl Cooks!
I covered the canner, and brought the water to a boil. I processed the raspberry jam for 10 minutes (after it came to a boil).

Raspberry Jam / The Grateful Girl Cooks!
When processing time was done, I turned off heat, waited for a minute or so, removed lid, then removed jars (using canning tongs), and set them on a dish towel to cool.

Raspberry Jam / The Grateful Girl Cooks!
I let the jars sit, undisturbed on the dish towel for 24 hours, listening for the tell-tale “PING” sounds, which means the jars have sealed. (I also checked the seal once jars were cool, by lightly pressing on the middle of the lid with my finger. If the jar did not seal, the lid will spring back… if that happens, you must refrigerate that jar of jam. After 24 hours, I put all the jars of jam into our pantry, to use up throughout the year and to give as gifts. Just yesterday, I gave a jar to my next door neighbor

That’s it… a little bit of time guarantees us absolutely delicious, fresh raspberry jam all year long! YAY!  Sure hope you’ll give this recipe a try!

Making Raspberry Jam is great way to "put up" those fresh, summer raspberries!
Category: Jam
Servings: 10 cups
Author: JB at The Grateful Girl Cooks!
  • 6 cups of crushed raspberries (measure AFTER crushing them)
  • 8 1/2 cups granulated sugar
  • 1 box Classic (powdered) Pectin
  1. Fill a boiling water canner half full of water. Bring this to a simmer. (At the same time, I start a teapot with water going, so I will have boiling water for the jar lids later on)
  2. Wash jars and lids in soapy hot water. Put lids in small bowl. Fill jars with water and put in canner on a rack, while it is simmering, to keep jars warm. (Or you can set jars on dish towel on a cookie sheet and keep in oven at 250 degrees for 20 minutes for same effect).
  3. In a large bowl, measure out the exact amount of sugar. Set aside.
  4. Crush the raspberries, one cup at a time, until you have 6 cups of mashed berries. Put the berries into a large stock pot.
  5. Stir the box of Pectin into the berries. Bring the raspberry mixture to a full rolling boil on high heat, stirring constantly (a rolling boil is when it is boiling hard, so that it won't stop bubbling even when stirred).
  6. Stir in all of the sugar quickly (all at once). Stir well to combine.
  7. At this point, I pour boiling water over the jar lids that are in the little bowl. Let them just sit in the hot water for 5 minutes while you finish the jam.
  8. Bring the jam/pectin/sugar mixture back to a full, rolling boil. Once it is a full rolling boil, boil it for exactly 4 minutes, stirring constantly. When time is up, remove pan from heat, then skim off any accumulated foam (and discard foam).
  9. Ladle the hot jam mixture into hot, prepared jars. Fill the jars, but leave 1/8 inch headspace at the top of each jar. Insert a plastic knife into each jar a couple times to help remove air bubbles. Adjust the headspace if necessary.
  10. Use a damp cloth or paper towel to wipe down the rim and edges of the jar. You need it free of debris in order to get a good seal on the jar.
  11. Cover the jars with the hot, flat jar lid. Screw on the jar rings tightly.
  12. Lower each of the jars onto an elevated rack in the canner. The jars must be completely covered with water, and must have at least an inch of water over the top of the jar. Add more boiling water to canner, if necessary, to make sure.
  13. Cover the canner; bring to a gentle boil. Once the water is boiling, process the jars for 10 minutes.
  14. When done, wait for a minute, carefully remove canner lid (lift lid away from you because of steam); carefully lift each jar out of water (with canning tongs), and place on dish towel on the counter to cool (do not put jars directly on counter cause you don't want temperature differences to possibly crack jars). You should hear "ping" sound as the jars seal properly.
  15. After the jars cool off, you can check to see they sealed properly by pressing the middle of the lid. The jar should NOT spring back when touched. If it does spring back, then you will need to refrigerate that particular jar. Let the sealed jars stand at room temp for 24 hours, then store unopened in a cool, dark place for up to 1 year.
Recipe Notes
FYI-The ten cups of jam this recipe produced filled the equivalent of 10 half-pint jars.
