Begin by making the sauce Romesco, put the almonds and soaked chillies in a food processor and pulse until roughly chopped. Add the garlic, peppers and spices and pulse again to combine.
Add the vinegar, olive oil and pinch of salt, pulse again to produce a thick sauce that is neither too chunky of too smooth.
Fry the hake fillets skin side down until lightly golden turn and transfer the pan to a hot oven. Roast the fish for about 5 minutes until just cooked through.
Whilst the hake is roasting put the garlic, olive oil, finely sliced dried chilli and pinch of salt into a small pan and put on a medium heat.
Cook gently stirring occasionally to distribute the garlic and chilli, as soon as the edges of the garlic begin to turn golden remove from the heat and allow to cool slightly, add a splash of sweet vinegar and the chopped parsley.
Remove the hake from the oven, put a fillet on each plate and peel away the skin, Immediately spoon a little sauce over each piece of fish and serve with a spoon of Romesco sauce.
