In a bowl mash the strawberries using a potato masher or fork.
In a large skillet stir together the mashed berries, sugar, pectin and lemon juice (starting with 2/3 cup sugar and adding in more desired I found that 2/3 cup plenty for me!) boil until slightly thickened about 5 minutes, add in a couple drops of red food colouring if needed.
Transfer the mixture to a bowl to cool.
Store tightly covered in a glass jar in the refrigerator until ready to serve.
