Place the clean dry basil leaves together with the garlic cloves (remove the germ first), salt and Parmesan cheese into the bowl of the food processor, and give it a whizz.

With the motor still running, add the oil as if you were making mayonnaise. Blend until you have a smooth sauce Now your pesto's ready, set it aside.

Add a drizzle of virgin olive oil to a nice hot pan, season the hake fillets with salt-and-pepper and cook.

Now we have all the ingredients prepared and there's just one more important step - getting the dish ready to serve. So place the hake fillets on a serving dish, and spread with the pesto.

If you like a slightly crispy top, you can pop the hake fillets in the oven for a few minutes. Or if you prefer, skip this step and serve right away.
