Dilute agar gelatin in 2 tablespoons of cold milk.
In a saucepan heat the milk, sour cream, lemon peel, vanilla and sweetener.
When it comes to a boil, add gelatin, mix and cook for 2 minutes.
Pour into molds - I used silicone muffin tins.
I put some fruit on the bottom of the molds.
Allow to cool and refrigerate for 3-4 hours.
Prepare the berry coulis sauce.
In a saucepan mix the fruit with a tablespoon of sweetener, 4 tablespoons of water and lemon juice.
Lightly crush them with a fork and let them boil for 3 minutes.
Reserve and allow to cool completely.
When they are well caught, take them out of the molds and serve with coulis.
Garnish with fresh mint and serve.
