Bring milk, fat, sugar, salt and lemon peel to the boil. Add the flour at once and stir until the mixture separates from the bottom of the pot as a dumpling. Pour into a bowl. Stir in an egg immediately.
Stir in the remaining eggs one by one when the mixture has cooled down. Pour the dough into a piping bag with a large star-shaped spout. Spray circles (approx. 6 cm Ø) onto baking paper coated with oil. Pour into the hot clarified butter (approx. 180°C) with the upper half facing down.
Loosen the baking paper while doing so. Bake for approx. 4 minutes until golden brown, turning once. Drain on a cake rack. Warm up the apricot jam. Coat the nests with it and let them dry. Mix icing sugar and lemon juice to a glaze.
Spread the pastry with it as well.
