Rinse the strawberries and remove the stems, cut into smaller pieces and place in a pot. Add water, lemon juice, honey and ginger. Bring to a boil then blend, strain through a sieve (rub through with the back of a spoon), season with sugar if needed. Chill well.
Serve in small bowls or wide plates with yogurt added (mixed with a spoon beforehand), sprinkle with fresh mint.
