Step 1

Put a pot of water on to boil for the pasta. Add salt once it starts to boil and bring to the boil again.

Step 2

Wash and chop the parsley. Drain the oil from the tuna. Rinse the anchovies well if they are salted. Cut them into small pieces and together with ¾ of the tuna, puree in a blender with a little of the beef broth.

Step 3

Put this sauce into a saucepan and add the rest of the broth and a few pink and black peppercorns. Stir and cook over a low heat until the sauce reduces and thickens (5-10 minutes). Add the rest of the tuna to the sauce and stir to mix in. Add salt to taste.

Step 4

Cook the vermicelli al dente according to the instructions on the packet, save a cup of the pasta cooking water and drain the pasta. Return it to the pot or put it in a bowl and add the butter, olive oil and chopped parsley. Toss to mix well.

Step 5

Then add the tuna and anchovy sauce, mix everything together well. Return to the heat and cook for another minute to allow the pasta to absorb the flavours of the sauce. If the sauce seems dry, add some pasta cooking water. Serve immediately with a little more chopped parsley and a few peppercorns.
