As the gnocchi cooks, add the shrimp in with the garlic and chorizo. Season with pepper and a tiny pinch of salt. Add a pinch of smoked paprika. Stir everything together. Add a couple of spoons of the cooking water from the gnocchi in with the prawns to deglaze the pan. Turn down the heat to medium low. Drain off the gnocchi once cooked (they will be floating to the surface of the water).
