Place cleaned hulled strawberries in a medium sauce pan with sugar, lemon juice & zest.
Cook on low heat till the sugar is completely dissolved. Next, slowly turn up the heat and bring to a boil. As you stir the bubbling jam mixture, start to smash the whole strawberries until jam is thickened for about 10 minutes.
One jam is at desired consistency, transfer to a jar and let cool for a bit at room temperature. Once cooled, seal your jam and place it in the refrigerator. Enjoy!
