Place the strawberries into a medium saucepan and begin cooking over medium heat.
As the strawberries warm, use a wooden spoon to mash some of them, releasing their juices and creating a slightly chunky mixture.
Add the lemon juice to the saucepan, stirring to combine. The mixture should start simmering gently with a fragrant citrus aroma.
Reduce the heat to low and let the sauce simmer, stirring occasionally, for about 10-15 minutes until the strawberries break down further and the sauce thickens slightly.
Stir in the chopped mint, allowing the herbal aroma to infuse into the sauce for a couple of minutes.
Remove the saucepan from the heat and let the sauce cool slightly; it will thicken more as it cools, developing a glossy appearance.
