Add strawberries and sugar to a saucepan and mix well.
Heat ingredients over medium heat and bring the mixture to a boil. I softly chopped the strawberries with my mixing spoon to break up the strawberries and get a smoother jam, but it is not necessary.
Once boiling, add lemon juice. Stir to combine.
Boil for ~15 minutes (or until the jam reaches 220F), stirring often so strawberries do not burn. If keeping in pantry jump down to Step 7.
Once done, carefully fill mason jar (I used a wide mouth funnel) and allow to cool.
Cover and refrigerate (lasts around 2 weeks).
If keeping in pantry:
Boil enough water to cover your mason jar and lid. This will sterilize it. When jam is ready to be removed from heat, carefully remove mason jar and lid.
Carefully pour jam into the mason jar (I used a wide mouth funnel).
Place lid on and turn over the jar. Leave upside down for 10 minutes.
This will seal the jam and allow you to store it in the pantry/counter/etc.
Refrigerate after opening.
Notes
*If you don’t plan on eating the jam immediately, this is for storing in pantry.
