Add strawberries (fresh or frozen), sugar, water, lemon juice, and salt to a saucepan. Stir to combine, then turn the heat to high and bring to a boil.
Once boiling, use a potato masher to gently mash the strawberries to bring out extra strawberry flavor.
Turn the heat down to medium low, and let the mixture simmer for 10 minutes.
Carefully scoop out the strawberry pieces using a strainer and place in a separate bowl.
Once the strawberries pieces are removed, pour the syrup through the strainer to remove any thick jelly-like texture. Repeat 2-3 times.
Let the Homemade Strawberry Syrup cool at room temperature for at least an hour before adding a lid and storing in the fridge for up to 3 weeks.
Add the leftover mashed strawberries to a container and place in the fridge to be used on top of pancakes/waffles/french toast/ice cream, or as an addition to mocktails and drinks.
