This delightful dessert is as easy to make as it is sugary sweet.
In large sauce pan, whisk together lemon juice, water, sugar, egg whites and egg yolk until smooth. Bring to a simmer over medium-high heat, stirring continuously. Add lemon peel. Cook until thickened, approximately 8 minutes, or until mixture is light yellow and coats the back of a spoon. Do not boil. Take out the lemon peel.
Remove from heat and pour the mixture into china dishes. Refrigerate until serving.
Serves 4.
