After that remove the spoon and press the tail to crack it. Then remove the shell. Now separate the claws from the knees. Then twist the finger and pull it out together with the swords. Be sure to pull out both swords. Now crack the claw open with the back of a knife and pull out the meat. Then cut the knees open with a scissor and remove the meat as well. Now portion the lobster tail and check the inside for any intensions. Then chop the knees and the claws into a fine tartare. Keep the lobster in your fridge for later.

5 grams

salt

25 grams

Transfer the flour on your worktop and make a well in the middle. Fill it with the semolina flour, the salt, the olive oil and the egg yolk. Now knead it into a nice dough, this takes around 5 minutes. Then cover the dough and let it rest in your fridge for at least 1 hour. Meanwhile let’s make the filling. Take the chopped lobster and add some celeriac cream and lemon zest. Then chop some chives and add it to the lobster as well. Mix this. After that dust your worktop with flour and roll out the pasta dough. Roll it till the thickness is around 2 millimeters. Then cut the dough with a round cutter. Now remove the excess dough and place a teaspoon of the filling on the middle of each circle. Then brush some egg wash around the filling. This is one part egg yolk and one part water.

Start with seasoning some boiling water with salt. Then brush a thin layer of the lobster butter on the lobster tail and sprinkle some flaky salt on top. Heat it up at 90 degrees Celsius for 7 to 8 minutes. Meanwhile boil the tortellini for 2 minutes. Once cooked transfer them on a tray. Then keep some of the pasta water for later and drain the rest. Now pour around 20 grams of the lobster butter in the saucepan and also add the pasta water. Reduce this till a thicker sauce starts to for. Then add the chopped chives and the cooked tortellini. Give it a good hustle. Then take the hot celeriac cream and make a circle on a plate. Place half a lobster tail on the side and the tortellini on the other side. Add a tablespoon of the sauce and pipe a big dot of the celeriac cream in between the tortellini. Then decorate with the sweet and sour celeriac and some garden purslane.
