Sort the blueberries, rinse with cold water and dab dry. Wash the lime thoroughly, dab dry and rub the peel. Squeeze the juice. Pour milk into a tall mixing bowl. Add cream powder and whisk briefly with the whisks of the hand mixer, then whip until creamy for 3 minutes at highest setting.
Add the lime zest and juice. Prepare the omelette dough in two portions so that the dough does not stand so long. Separate three eggs, beat the egg whites and a pinch of salt until very stiff. Sprinkle 15 g sugar into each portion.
Twenty grams of starch seven. Fold the starch and egg yolk into the beaten egg white. Melt 10 g fat in a pan. Add half of the egg mixture, smooth it down and bake at low heat covered for about 10 minutes until golden brown.
Bake the rest of the egg mass in the same way. Prepare 2 omelettes from the remaining ingredients. Spread one half of the omelette with the lime cream. Sprinkle a quarter of the blueberries on top, fold the omelette and dust with icing sugar.
