Put the strawberries and sugar in a medium bowl. Stir well to combine. Set aside in the fridge for 30 to 45 minutes.
Remove the strawberries from the fridge, and with a potato masher (or fork), mash the strawberries until smooth.
Fold in the mascarpone, cinnamon, salt and cognac (if using). Stir well to incorporate. Store in an airtight container in the fridge.
Serve on top of toasted, crusty bread with strawberries and mint.
