FREE CALCULATOR CONTEST! IT’S WORTH IT, TRUST ME.
Way back in the day, I remember my mom would sometimes make homemade strawberry jam. We would spread it on our week-old bread, crying with happiness as the sweet fruit preserves covered up the normal moldy taste of our bread. An added bonus is that when it’s homemade strawberry jam, you can use organic, local strawberries and also reuse some old glass jars, instead of getting strawberries from who-knows-where and a brand new glass jar.
After much Internet (and soul) searching, I decided to share this secret homemade strawberry jam recipe. Unlike my recipe for homemade protein bars, this actually requires using the stove, so get an adult’s supervision!!!!!
Get a Glass Jar
I was lucky enough to get about 6 glass jars for free off of freecycle. Maybe you have some old pickle or jelly jars sitting around that you could use. If you want to sterilize your glass jars, you can fill them about 3/4 full of water, put the jar in a shallow pan of water, and let it simmer for about 10 minutes.
Get Strawberries
If you get some organic, locally grown strawberries, then congratulations, for you are on your way to becoming an eco hero. Get a quart of strawberries, and rinse them and chop off their leaves.
Get Sugar
Let me take this time to say that this is not a diabetic-safe strawberry jam, no sirree. This recipe calls for a quart of sugar. They recommend that the sugar is warm; I put mine in the oven at a very low temperature for about 5 minutes.
Boil Them Strawberries
Put all the strawberries into a big (10 quart) pan, and begin simmering them. If they seem too dry, mash up a few of them to let their juices out. Once some juice is in the pan, then it’s time to…
Add the Sugar
Pour the warm sugar over the strawberries, and stir the heck out of this sticky mess. Once you get the sugar and strawberries and juice integrated into a homogeneous mixture, cover the pan and let it simmer.
Boil for 15 Minutes
This is a dangerous step in this homemade strawberry jam recipe that has killed dozens, if not hundreds, and it answers the question of why you need such a big pan for such a small amount of strawberries and sugar. I found out the hard way that if you boil strawberry jam, it gets HUGE, and it overflows if you take your eyes off it. I had to lift up the lid and turn down the heat some to control the rising bubbling mixture.
WARNING: Cleaning strawberry jam out of the inside of a stove isn’t as fun as you might think.
Cool it and Plop it in a Jar
Turn off the heat after 15 minutes and let the pan cool on an oven mitt. You can add a tablespoon of lemon juice if you want (it gives it some “kick”, if you will). Hopefully you’ll see it slowly thickening. Once it’s pretty cool, you can put your new homemade strawberry jam into the sterilized glass jars and bah-bam, you are done.
P.S. I used a recipe out of the 1960 version of The Joy of Cooking. Apparently, we know more about germs than they did back then, so the open kettle method of canning is no longer considered safe. This here article explains why in vivid, shocking detail.

Thanks for your comment on my site. At some point I made some open kettle jam…it turned out great and was so easy! Too bad we’re not supposed to do it that way anymore, right?

For true, this kind of jam is for people who are X-treme and like to laugh in the face of death.

Looks great! I am sure you are living on the edge with this method though
Mine tastes great, and I am still alive and kicking (so far)

Good lo’dy, homemade strawberry jam is the bomb diggity. I eat it everyday.

home made but not home grown!
there’s nothing green about such an inefficient process.
August 20th, 2008 at 12:47 pm
Even if you don’t grow them yourself, it’s still “green” to use some strawberries from a local farmers’ market. Speaking of inefficient processes, how ’bout them farm subsidies, farmer Jack?

I will definately have to try this while local strawberries can still be found (w/o the sugar for me). Thanks for posting!

Dang, I have no idea if you can make this without sugar, so por favor let me know how it goes.

I have a huge strawberry garden in my yard and every year sadly some of them go to waste. But not this year I decided to make preserves. Thanks for the idea.
