Once you eat homemade jam, it’s hard to go back to store-bought. Homemade is just so much better, and there’s only two ingredients, so you know what you’re getting.

Why Make Strawberry Jam Without Pectin?

A lot of recipes call for pectin when making strawberry jam, which can help fruit juices thicken and set.

While pectin can be an effective and convenient way to achieve the desired consistency, it can also alter the taste and texture of the jam.

Some people find that pectin can add a slightly artificial flavor or a gel-like texture that is not tasty.

By making strawberry jam without any pectin, you have full control over the ingredients and can create a jam that is truly homemade and bursting with natural flavors.

Strawberries do have a low amount of natural pectin, so it will set up without added pectin.

My husband, John, picked up a large tray of strawberries at a local fruit market for me. When he came home, he had them sitting in a large box, and I laughed.

I couldn’t imagine that we would need that many strawberries. I was totally wrong. We ended up using every bit of those berries. The picture below is about 1/10th of what we used.

I got the recipe from an old Ball Blue Book Guide To Home Canning and gave it a little bit of my own tweak. The book is a super fun guide to look through.

I felt like I was stepping back in time after reading some of the recipes. And, to top it off, the pages were yellowed and used. I knew I would cherish it all the more.

The authors of the Ball Blue Book Guide to Home Canning even spell syrup, ‘sirup’ in the cookbook. I felt all southern just sayin’ it!

So, as I started mashing the strawberries, I realized how weak my arms really are. These babies need some more muscle. No wonder my grandmother had biceps to die for.

Once the mashing was all done, I started to cook the strawberries. All I can say is, thank goodness for air conditioning. That is a hot job standing there for an hour. (But so worth it).

Homemade Strawberry Jam Recipe Step-By-Step Instructions

Boiling jars in a large saucepan.

Place jars and lids in a large saucepan of water and bring to a boil. Boil for about 10 minutes to sterilize them. Then, take them out and let them dry. Be careful as they are VERY hot jars.

Cleaning strawberries.

Rinse the strawberries and cut off the tops. Place the strawberries into a large bowl to keep the juices from escaping while you crush them.

Then crush the strawberries. I used a potato masher and that worked great.

Add the strawberries and sugar to a large saucepan. Slowly bring to a full rolling boil and stir occasionally.

Keep cooking rapidly for about 40 minutes. As it thickens, stir often so it doesn’t stick to the pan. Don’t go far while the jam cooks because you don’t want it to stick to the bottom.

Pouring strawberry jam into a jar with a large ladle.

Carefully ladle the hot jam into the jars, leaving about 1/4 inch of headspace at the top. This will allow the jam to expand slightly as it cools.

Use a clean, damp cloth to wipe any spilled jam from the rim of the jar, as this can prevent a proper seal. Place the lids on the jars and tighten them securely.

If you prefer, you can also use a water bath canner method to seal the jars. Simply place the filled jars in a large pot of boiling water and process them for about 10-15 minutes.

(Don’t hold the jar like the picture above as it will be very hot jam).

Allow the jars to cool completely at room temperature, then check the lids to ensure they are properly sealed. You should hear a popping sound as the lids seal.

Once you hear them pop they have a good seal.

If any of the lids do not seal, refrigerate those jars and eat the jam within a few weeks. Properly sealed jars can be stored in a cool, dark place such as a pantry for up to a year.

Once you open the jars, store the jam in the refrigerator and eat it within a month for the best flavor and quality.

Once the jars are filled and sealed, you need to store them properly to ensure the jam stays fresh and delicious.

You can purchase a canning set on Amazon to make things a little easier.

Frequently Asked Questions About Making Jam Without Pectin

Can I use frozen strawberries to make jam without pectin?

Yes, you can use frozen strawberries. However, keep in mind that frozen strawberries may release more liquid during the cooking process, so you may need to adjust the cooking time slightly.

Can I reduce the amount of sugar in the recipe?

Yes, you can reduce the amount of sugar in the recipe to suit your taste preferences. Just keep in mind that sugar not only adds sweetness but also helps with the preservation and texture of the jam.

My jam didn’t set properly. What did I do wrong?

If your jam didn’t set properly, it may be due to undercooking or using underripe strawberries. You can try cooking the jam for a bit longer or adding a bit more lemon juice or apple cider vinegar to help with the setting process.
