Hana,
An Australian low carb forum member makes perfect meringues with a mix of Stevia and Erythritol.
Low Carb Meringue
(using my food processor that has a egg white whisk)
4 large egg whites or 5 small
1/2 tsp Cream Of Tartar
1/3 cup erythritol
1/8 tsp Stevia
1 tsp Vinegar
2 tsp Cornflour
1/2 tsp Vanilla Extract
pinch of salt
Beats egg whites with C of T til stiff. Add sweeteners slowly til glossy, approx 8 minutes. Add salt,cornflour,vanilla and vinegar untill just combined. Spoon onto greased baking paper into 6 mounds, flatten slightly. Bake at 120 C for 2 hours then cool in oven to dry out.
Lovely crisp shell outside, soft meringue inside (not marshmallow), good sweet flavor no bitterness from the stevia.
