This has to be my favorite time of the year. Summer’s oppressive heat and humidity isn’t here yet, so it’s enjoyable to spend time outside and can’t think of anything more fun to do than pick strawberries. I can remember years back picking strawberries with my family where my motto was always “one for me, one for the basket”. Luckily they never weighed me on the way out.
It’s impossible to beat the sweetness of a freshly picked strawberry, but you can preserve most of it with a bit of culinary magic by making strawberry jam. In this tutorial I’ll not only provide you with an easy strawberry jam recipe, but also show you step by step how to can it so you can enjoy that strawberry flavor throughout the year.
Strawberry Jam Recipe
3 3/4 C Crushed Strawberries
1/4 C Lemon Juice (Freshly Squeezed)
7 C Sugar
1 Package Liquid Pectin
1 Tablespoon Butter (optional)
1. Wash and Hull the Strawberries
Strawberries are generally pretty dirty little bastards, so make sure to give them a good washing. This is also a great time to get rid of any questionable strawberries as well as cutting off any parts that you wouldn’t want to be eating. Any piece of rotten strawberry getting into your jam can easily spoil an entire batch of jam.
Once clean, hull your strawberries making sure to remove any pieces of white. If you’re strawberries are large, you can cut them in half at this point.
2. Smash the crap out of those berries
Now’s the time to get out your pent up frustrations because you need to smash your berries so that you have a good mix of berry chunks and juice. While you could use a food processor, blender or food mill, I prefer my good old potato masher so that there are still some considerable chunks left.
3. Add the berries, lemon juice and sugar to a pot. Stir to combine.
4. Gently heat up the berry mix.
Put the pot with your mixture on medium heat and stir to incorporate everything. You can add, if you’re so inclined, the butter here to reduce foaming later in the process.
5. Get set for canning
While the strawberry mix is heating up, get things set for canning. Get your largest pot of water boiling and put in your cleaned jars. This allows them to heat up so that when you put in the hot strawberry jam they don’t explode. So yeah, don’t forget this part. Also too, take your lids and put them into a small pot with water on medium heat.
I also like to take this as an opportunity to make sure I’ve got everything I need for canning, because once things get going, a missing component could be a disaster. So get out your funnel, bands and canning tongs.
6. Get the strawberry mixture boiling.
Turn up the heat on the strawberry mixture to high so that it comes to a boil. Be careful here as this can pop and splatter, and it’s hotter than hell. It could make for a cool body modification, but I’d prefer a tattoo.
Stir continually to prevent burning. You’ll know when it’s reached the right point when stirring no longer dissipates a boil.
7. Pour in the liquid pectin.
The strawberry mixture should be at a roaring boil and now it’s time to put in the pectin. Make sure you get it all out of the package, and stir it in. Now let this mixture continue to boil for one minute.
8. Take the strawberry jam mix off of the heat.
9. Take your jars out of the canner and set them aside to drain.
10. Start filling your jars.
I use a big funnel for this because I like my counter tops, but I know a lot of folks who just pour it in and wipe off the rims later. Fill up each jar all the way to 1/4 from the top. Do this for each jar until you’re out of your jam mixture.
11.Seal the jars.
Once all of your jars are filled, wipe off any jam that you may have gotten on the rims. One by one, take the lids out of the hot water with tongs and set them on top of the jars. Either using tongs or a towel to protect your hand, fasten the band on the jar.
12. Can those suckers.
Carefully place your jars in boiling water. They’ll need to take a bath for 10 minutes before they are ready. Once you’ve hit the 10 minute mark, remove them from the water and place them on a towel.
13. Bask in your jammy awesomeness.
You’re done. You just have to wait 12 – 24 hours before your jam sets up, but don’t fret, it will be about that long before these damn things are cool enough to handle again. You’ll notice that one of these things in the picture does not belong. That little guy on the right with the plastic wrap on it was my left over jam and since I will be eating it within the next few days, there was no need to can it. Stored in the fridge it will last at least a month.
You strawberry jam will last canned for a least a year, but I’ve kept some jars much longer with no issues. There are a couple of things to make sure of though to prevent yourself from dying from tainted jam. Never store the jars with the bands on because if the lid were to pop off (a good sign the stuff is spoiled) you’d never know. Also, be sure to keep these in a dark, cool area as light can effect the product.
One note of caution: Beware of sharing your supply with friends and family as once they know you make strawberry jam from scratch, they’ll be asking for it every year.

Hey Urban,
If he wants 7 cups of sugar in his jam, it’s nobody’s business but his!

The sugar is the preservative. Also, my mom has been making jam for 60 years, and uses paraffin wax to top the jam before sealing with lid and band. She does NOT use a water bath. Umm! Peach, strawberry, blackberry, blueberry…At some point I’m going to be taking over on the jam making, so I have learned her method. Besides, it is great fun to suck on the wax, a little, after removing it from the jar.

Hello,
My jam did not set. What should I do differently next time I make strawberry jam to assure that it will set?

Hey Julie,
Cooking the mix to the right temperature for the right amount of time is key. You can’t undercook it and you can’t over cook it or it won’t set properly. Also, a very humid kitchen can mess with things.
I’d make sure to follow the instructions to a T next time, using a candy thermometer if you didn’t before. Also, it’s good to test it while you’re making it: once you think your mixture is done, drop a few drops on a cold plate. It should set-up quickly and if you push your finger through it, the skin on top should wrinkle up.
If you still have the jam that didn’t set, you can try to salvage it. You can boil it again for a few minutes or try adding some pectin and boiling it again. If those don’t work, you can always use the jam as a sauce for ice cream.

I’ve used this recipe several times, always with great results! I do modify it a bit – ReaLemon instead of fresh squeezed and I had just a sprinkle of powdered pectin. Also, instead of boiling the jars I run them through the dishwasher, they are super hot and ready about the same time the jam is. I have referred several people to this page for the recipe. Super yummy! Thanks so much for sharing your recipe.

I agree with you as to putting wax on jam in stead of a water bath. Could you please send me your recipe the way you do it. Much appreciated. Thanks so much. Bobbie.
