Add all ingredients to a medium size sauce pan. Heat over medium heat and bring to a boil, stirring occasionally.
Once the mixture is boiling, reduce heat and allow to simmer for about 15 minutes, while stirring throughout.
The berries will soften and will make juice.
After the 15 minutes, remove the pot from the heat and mash the strawberries to desired consistency. Cover the pot and allow to cool for about 10 minutes. Spoon into a jar and store covered in the fridge for up to 2 weeks.
