If you don't use sugar, this is a low carb recipe, so don't fear the fat! This recipe requires raw egg, so make sure you have grass fed fresh eggs. I'm not totally sure about the amount of sweetener because I don't like it too sweet. I used a mixture of powdered xylitol and erythritol and a glycerine based liquid stevia. Maybe you have to try a bit until you get the right amount of sweetness - especially if your strawberries are sweeter than mine were!
Cooking time is chilling time!
1Puree mascarpone with half of the strawberries, the juice and zest of the lemon, the stevia drops and one half tablespoon powdered sugar or xylitol or erythritol. Depending on the liquid stevia you use, it might be necessary to adjust and use more or less. Start with ten drops and then taste - my strawberries were not really sweet, so I used the full 15 drops.
2Divide egg, beat egg white stiff, adding the other 1/2 tablespoon sugar as soon as the white becomes shiny. Continue beating until stiff peaks form.
3Cream egg yolk with remaining tablespoon of sugar or xylitol or erythritol. It should be a pale yellow cream.
4Fold creamed egg yolk into mascarpone cream, then gently fold in the stiff egg white. Combine and chill for at least one hour.
5For serving, dice the remaining strawberries and divide between four small bowls. Top with mascarpone cream and serve immediately.
