Rinse your strawberries, remove the tops, and slice them into quarters.
Add the sliced berries, sugar, and lemon juice to a pot and cook on medium heat until it begins to boil, stirring frequently.
Cook for about 25 minutes. While it is boiling, smash some of the larger strawberries with the back of a spoon.
After 25 minutes, your jam should reach 220℉ (use a candy thermometer to test).
For another test, or if you don't have a candy thermometer - set a plate in the freezer for about one minute.
Drop a quarter-sized amount of the hot preserves onto the plate and put back in the freezer for another minute.
If you can run your finger through and it wrinkles up (aka, the preserves don't quickly fill the path you made with your finger), your preserves are ready!
Add the hot strawberry preserves to a mason jar and let it cool completely.
Once the preserves are cooled, seal, and store in the fridge.
Serve on biscuits, toast, pancakes, or anything else you can think of. Enjoy!
