Start by making the romesco sauce. Blend together all the ingredients apart from the olive oil. It should be still slightly chunky
While the blender is running, drizzle in the olive oil in a continuous stream until the sauce is almost completely smooth. Season with salt and pepper then set aside until needed
Next, mix together all the ingredients for the smoked paprika salt
Cook the pasta according to package instructions in a generous amount of salted water, or until al dente. Stir occasionally to prevent sticking. Before draining, reserve about 150 ml of the starchy pasta water – this will help loosen the sauce later
For the chorizo, heat the groundnut oil in a pan over medium heat, then add the chorizo. Cook, stirring occasionally, until the edges are crisp and golden brown, about 5-7 minutes. Remove from heat and set aside
Add the pasta, romesco, a splash of the reserved pasta water and the double cream, then stir until fully combined
Serve topped with the crispy chorizo and capers. Finish with parmesan shavings, a sprinkle of the smoked paprika salt and some black pepper
