In a small saucepan over medium heat, add the strawberries, water and sugar. Simmer for about 5 minutes or until the berries soften and remove from the heat.
Allow the strawberries to cool completely and then puree.
Once the mixture is cool, whip the cream and vanilla together for about two minutes to make a soft whipped cream.
Fold in the strawberries and then pour into the molds. Freeze for 4 hours or until set.
Notes
If you prefer, you can substitute yogurt for the whipping cream.
