This is a repost with an update. I decided to try Ball’s Natural Gel No Sugar Needed Fruit Pectin ($1.56 at Walmart. There is a .50 cent coupon inside, so you can buy one then use the coupon to buy the next one if you like it). With this pectin adding sugar is optional. You use fruit juice as the primary sweetener rather than sugar. I ended up adding 1 cup of sugar to my strawberry jam and 1/2 cup to the mixed berry jam (which is still a lot less than the 3 cups in traditional recipes). The jam is still a little tart, but my family actually prefers the tartness to overly sweet jam.
How to Make Homemade Jam with Less Sugar
Basic Recipe for No-Sugar-Added Homemade Jam:
4 Cups mashed fruit (for the mixed berry I used 2 C strawberries, 1 C raspberries, and 1 C blackberries)
1 Cup Unsweetened fruit juice (apple and white grape are the sweetest juices, but I used cranberry/pomegranate)
1 1.75 pkg. Ball No Sugar Needed Fruit Pectin
~ 1/2 – 1 1/2 Cups of sugar ( add to the taste your family prefers)
1/2 teaspoon butter
Update: The last time I made jam I used 1 cup of thawed fruit juice concentrate, instead of fruit juice, and did not need to add any sugar. I realize that there is “sugar” in the fruit juice concentrate, but my husband prefers that I not add refined sugar to his jam.
Items that you Need:
Boiling Water Canner or a large deep sauce pot, with a lid, and a rack (the first few times I canned I did not have a canner or a rack. I just put the insert from my pressure cooker on the bottom of a deep pot.)
6 – 8 ounce, clean, glass jars with NEW lids and bands (the lids can not be reused, which of course causes me pain. If anyone has come up with a second life for jar lids please let me know!)
Nice to have, but not required (these are all in the above picture):
Wide Mouth Funnel
Jar Lifter
Lid Lifter
Headspace Tool



Add sugar to taste. Return mixture to a full, rolling boil. Boil hard for 3 minutes, stirring constantly. Remove from heat. Skim foam if you didn’t put in butter.

When the jam is done, I pull the jars and lids out of the canner and quickly dry them (but I don’t worry about getting every drop of water). Ladle the hot jam into the hot jars, leaving 1/4 inch of head space. Clean any jam from the rim and threads with a clean, damp cloth.
Center the hot lids on the jars. Apply bands and tighten until they are fingertip tight.

After the processing is complete, turn off the heat and remove the lid. Let jars set for 5 minutes.
Remove the jars from the canner and set upright on a towel to cool. Let them sit undisturbed for 12 – 24 hours.

If the jars are sealed, label them and store them in a cool, dry, dark place for up to a year.
Edited because I incorrectly confused the terms lids and bands in one of the above paragraphs. Sorry, I am operating on 5 hours of sleep!

Mub, I doubt I need to tell you, but I need to edit this post to say use a firm straw when hulling strawberries. I visited one of my friends and she was trying to hull with a flexible straw – didn't work so well…

Great Post! Thank you! I made some strawberry jame a few years ago and have been wanting to do it again. I have been waiting for the berries in our area to be ready for picking, hopefully I can go get some before the end of the week!

I'm learning all sorts of great things from your blog! I didn't know you could hull strawberries with a straw. I'm planning on making freezer jam in a couple of weeks and I can't wait to try that method out!

This looks so good! My mother-in-law used to make raspberry jam and it was delicious. Thanks for teaching us how to do it! 🙂

I haven't attempted jam since making peach jam years ago — but I may try this, as it looks good, and far far less sugar than typical concoctions. We have abundant strawberries, and later in the season we'll have grapes!

I hope you enjoy the jam when you have a chance to try it.

Saving for later use. TY
