Cook the tagliatelle in plenty of salted water until al dente.
Heat the butter in a saucepan and fry the finely chopped shallots in it until translucent. Dust the curry powder over it and stir in, immediately add the cream, otherwise the curry will be bitter. Reduce the sauce to about 2/3 over medium heat.
Add the washed and drained shrimps and cook only briefly while stirring so that they do not become hard. Season with salt and garnish with coriander greens if you like.
