Briefly boil 250 ml water, butter, salt and lemon peel. Pour in the flour at once and stir until the dough comes off the bottom of the pot as a lump. Pour the dough into a mixing bowl and allow to cool slightly. Stir in the eggs one after the other. Pour into a piping bag with a large star-shaped spout. Pour 9 cream puffs onto a baking tray lined with baking paper.
Bake in the preheated oven (electric cooker: 225 °C/ convection oven: 200 °C/ gas: level 4) for about 20 minutes. Cut a lid off each of the still warm cream puffs. Stir icing sugar and egg liqueur until smooth. Sprinkle the lid with the mixture and leave to dry. Mix espresso powder and 1 tablespoon of hot water, let it cool down. For the cream, whip cream and vanillin sugar until stiff. Stir in the espresso briefly. Also fill into a piping bag with star-shaped spout. Spray cream onto the cream puff bases. Dust the lid with icing sugar and place on the cream. Knead marzipan and food colouring. Form small eggs from it.
