We LOVE Fresh Strawberries!

I grow strawberries in my small backyard garden, and love to have them to snack on.  But when I am going to make jam, I usually end up going to a local U-Pick farm in the Spring and picking a large amount of them, as you can see from the photo below.

Regardless of how you “get” the strawberries (growing them, grocery store or picking them at a farm), jars of homemade strawberry jam are wonderful to have in the pantry to enjoy. It’s also great to have jars available to give as gifts throughout the year.

Fresh picked strawberries for jam

Strawberry Jam is canned for long term storage using a water bath canner.  While getting the jam made and ready for canning, you can begin heating the water in a canner, and prepping jars, lids and rings per manufacturer instructions, so everything is ready to go when the jam is ready.

How To Can Strawberry Jam

Start by placing clean and de-stemmed strawberries in a large bowl and crush them.  I use my potato masher to crush the fruit. You can also use a food processor for this, but do not puree the fruit. Use the pulse button to chop up the strawberries. You need small pieces of the strawberries in the jam!

Measure the exact amount of crushed fruit the recipe calls for into a large heavy saucepot.  Add fresh lemon juice and 1 box of powdered pectin into the fruit; stir to combine. I also add 1/2 teaspoon of butter to the fruit, which helps to keep the fruit from foaming too much while it cooks (but this is optional).

Measure exact amount of sugar into a separate bowl. Set aside until ready to add to the hot fruit mixture.

Cook The Strawberry Jam

Bring the strawberry mixture to a FULL ROLLING BOIL over High heat.  Stir mixture CONSTANTLY.  NOTE: A full rolling boil means that the strawberry mixture doesn’t stop boiling, even when you are stirring it). As soon as mixture comes to a full rolling boil, dump ALL the sugar in at once, and stir well, to combine.

Bring the jam mixture back to a FULL ROLLING BOIL, then let it boil for 4 minutes. Be sure to stir jam constantly so it won’t burn on the bottom of pan.  Remove pan from heat. Skim off any foam that appears on top of jam and discard.

Filling The Jars

Ladle the hot jam quickly into clean, pre-heated jars.  Fill each jar almost to top, leaving 1/8 inch headspace. Insert a non-metallic utensil into each jar two or three times to remove air bubbles, then adjust the headspace, if necessary.

Wipe the rims of each jar with a wet paper towel or clean dishcloth to remove any jam residue (residue would prevent jars from sealing properly). Cover each jar with prepared flat lid, add screw band and tighten to fingertip tightness. Place the hot jars (using canning tongs) onto a canning rack.

Processing Strawberry Jam

Lower rack into simmering water in canner (the reason the jars must be on a slightly elevated rack is so the jars don’t crack while in contact with direct heat on bottom of pan). Make sure the hot water completely covers the jar tops by a couple inches (add additional hot water if needed). Cover the canner.  Bring the water inside to a gentle boil. Once boiling, process the jam for 10 minutes.

When the processing time is complete, remove jars and place them upright on a dish towel until they have cooled completely. Do not place hot jars directly onto kitchen counter, because temperature variances could cause the jars to crack.

Test The Seal Before Storing The Jars

Once jars have completely cooled (12 hours or overnight), make sure to test the seal on the jars before storing in pantry. Press the middle part of the lid.  If the lid springs back, the seal is bad, and the jam will need to be stored in the refrigerator. If the jars have a good seal,  label and store in pantry, as they are now shelf stable. I unscrew and remove the rings before storing.

When ready to use, open up a jar, and spread some of that thick, sweet strawberry jam goodness on a piece of toast… and ENJOY the delicious work of your hands! Now you know how to can strawberry jam. YUM!

Spoonful of homemade, canned strawberry jam

Have a wonderful day!  Spring is just around the corner… can’t wait to get out there, pick some fresh delicious strawberries and make yummy strawberry jam! I’ve given away so many jars of homemade jam to friends and family recently, I need to make more just so WE can have some around to enjoy this year!  Go figure! Have a great day.

How To Can Strawberry Jam

7 Comments on How To Can Strawberry Jam

  1. Can you use less sugar?
    I made strawberry jam and followed the instructions on the sure jell box and it was too sweet.

  2. Hello,
    I recently made your blackberry jam recipe and loved it! I want to try making your strawberry jam as well but was wondering if you can make it in pints or just in half pints.
    Thank you!

    • Hi, Bryana… thanks for your note. Yes… you can most certainly make it in pint jars. Just remember you will have less jars of jam by doing that, obviously. I just canned more jars of the strawberry jam recently as well. YUM! Have a great day.

  3. Great recipe! This is my first time canning anything. I’ve done my research and ready to try my hand at it. I do have a question. How many ounces is the powdered pectin? It comes in a large bottle at Wal-Mart. However, they do have a box with two packets. Do I use both packets? Or how much do I use from the large bottle? Keep up the good work and have a great day!

    • Good morning, Annette! The amount of pectin (in the small box) is 2 ounces. Sorry for the confusion. I will add that amount to the ingredient list. Hope you have great success with making your very own strawberry jam! Once I learned how to can jam, I was hooked! Have a great day!

  4. Thank you so much for posting a jam/canning recipe. Canning and making jam seems so hard and intimidating; however, your simple instructions and detaled pictures makes it look like something I can do! 🙂 Thank you for your hard work!!!!! I love your site!!! I found your blog a couple days ago and had been exploring! You have so many goodies and yummy food that I feel like I found a treasure! Keep up your awesome work, delicious recipes and amazing pictures!

    • Thank you so very much for your kind words, Tonya! I appreciate so much the encouragement you brought to my heart this morning. I hope you have the opportunity to make some jam. When I made my FIRST jars of jam many years ago, I was terrified. Once they turned out fantastic, there was no stopping me! I wish the same for you. Have a blessed day, and thank you again for taking time out of your busy day to write. Love, JB (The Grateful Girl Cooks)
