Tonnato sauce (Italian tuna sauce) with sliced pork fillet

This is the easiest and most delectable cold sauce to put over thinly sliced pork fillet.
You can also use thinly sliced turkey, chicken, veal and even roasted peppers. It’s so versatile and I highly recommend it.

Serves 4

For the pork
8 cups chicken or vegetable broth
1lb pork fillet

For the sauce
3.5 oz a good brand of canned tuna in olive oil, drained
2 egg yolks
2 anchovy fillets
8 – 9 fl oz extra virgin olive oil
2 tbsp lemon juice
1 -2 tbsp capers
freshly ground pepper
chopped parsley to garnish

Pout the stock into a large saucepan and poach the pork fillet for 20 minutes until cooked through. Leave it to cool in the stock.
When the fillet is quite cold, remove them it the stock and slice thinly. Arrange on a serving plate.

Meanwhile, put the drained tuna into a food processor with the egg yolks and anchovy fillets. Turn the motor on and gradually add the olive oil in a very thin trickle.
Add the ground pepper and lemon juice, to taste
Spoon the sauce over the pork and scatter with capers
Garnish with parsley and serve
