Start by adding the chorizo to a large pan over a low heat with 1 tbsp of the extra virgin olive oil. Gently fry, allowing the fat to render from the chorizo slowly. Fry for around 8 minutes, until the seasoned fat is rendered and the chorizo is crispy.
Meanwhile, add your pasta to heavily salted (salty like the sea) boiling water. Set your timer to the packet time minus one minute.
Once the chorizo is crispy, remove ⅓ from the pan to use as a garnish. Add the garlic, smoked paprika, uncooked prawns and chilli flakes into the pan and gently fry over a medium heat for 2 minutes.
Transfer two ladles of pasta water into the pan with the chorizo and stir vigorously. Once your pasta timer goes off, reserve a generous amount of pasta water and transfer the pasta into the pan with the chorizo. Also add the parsley, 2 tbsp of extra virgin olive oil and lemon juice at this stage. Stir to get everything incorporated.
Serve with the reserved crispy chorizo, an optional extra lemon wedge, a sprinkle of parsley and extra chilli flakes if you like things spicy.
