This is a classic Canadian recipe. Simple and delicious. It's not thick, like pectin-based jams, but I think it's truer to the fruit and more delicious. Try it with Lemon-Walnut Scones - perfect pairing. ETA: Many people have asked me why this recipe contains butter. The butter prevents the jam from foaming while you're cooking it - the foam is unattractive and spoils the appearance of the jam. Adding a little butter eliminates this problem.
- 3 lbs fresh strawberries, washed and hulled (about 9 cups)
- 4 cups sugar
- 1⁄3 cup lemon juice
- 1 tablespoon unsalted butter (optional)
- In a large saucepan, bring strawberries up to a simmer over medium-low heat, mashing roughly with a potato masher or flat spoon.
- Add sugar and lemon juice, stir, and bring up to a simmer for 2 minutes.
- Add butter and bring to a vigorous boil, stirring often, and cook for 10 to 20 minutes, periodically measuring the viscosity of the jam by dabbing a spoonful onto a plate and tipping the plate.
- Once the jam slows its drip down the plate (it should no longer run like a syrup), remove from heat and skim off foam.
- Fill jars that have been washed, rinsed, dried and boiled in a pot of water for 3 minutes to 1/4 inch from the top.
- Fasten lids securely and boil jars in a vat of water (be sure jars are completely submerged) for 15 minutes.
- Remove jars with tongs and let cool upright.
- Check for secure seals on jars (lid should not spring when touched) and store in a cool place away from light for up to a year.
- Any jars that do not achieve a proper seal should be refrigerated.
This delicious recipe is written using old-fashioned methods, but rest assured it is perfectly safe to store unopened on the pantry shelf if processed using contemporary techniques (boiling water bath), so don't pass it by if you're concerned.

Amazing recipe!! I cooked it for 20-30 minutes after adding butter. Thickness tried on a cold dish. Drip, let it rest for 30 sec, let it run on the plate. If it does not run as a liquid, it's ready (will finish setting when cold). Tried also with Sour cherries, and had same results. I was able to make 6 250ml Mason Jars with these amounts.
This was my first time to make jam. I followed the recipe exactly, although I did put my imersion blender in the strawberries first. Delicious! My husband loves it. He has been using it on bread as jam and on ice cream as a sauce. The consistency is perfect, not to thick and not too thin.
