Bring 1/8 litre of water, fat and salt to the boil in a saucepan. Add the flour at once and stir until the mixture conglomerates into a lump and comes off the bottom of the pot. Pour into a bowl.
Stir the eggs one after the other into the mixture. Let rest for 30 minutes. Pour the dough into a piping bag with a large star-shaped spout. Spray in a spiral shape as a circle (22-24 cm Ø) onto a baking tray lined with baking paper.
Bake in the preheated oven (electric cooker: 200°C/ gas: level 3) for approx. 25 minutes. Cut the wreath with a knife and let it cool down. Meanwhile, put the raspberries on a plate and pick out about 100 g of nice raspberries and put them back into the freezer.
Defrost the rest of the raspberries. Soak the gelatine. Puree raspberries, pass through a sieve and stir in sugar. Squeeze the gelatine, dissolve and stir into the puree. Chill. Place the rest of the raspberries on kitchen paper and allow to thaw.
Whip the cream until stiff. When the raspberry puree thickens, fold in the cream and fill into a piping bag with star-shaped spout. Spray raspberry cream onto the lower choux pastry ring. Spread raspberries on top and place the upper ring on top.
Put it in a cool place. Melt the chocolate coating on a hot water bath. Chop the pistachios. Pour the chocolate coating into a freezer bag and cut off a small corner. Spray strips over the wreath and sprinkle with pistachios.
Allow to dry. Results in about 12 pieces.
