Mock Fish, also known as Pesce Finto in Italian, is a kind of mousse made with tuna and potatoes that is strictly fish-shaped, to be mainly served as a starter, eaten spread on crackers or bites of toasted bread or with breadsticks. 

Feel free to be creative by choosing what to garnish it with and what shape of fish to give it. That’s also fun to do playing with kids. 

Serves 6, Preparation 20 mins, Cooking time about 25 mins + 2 hrs in the fridge

  • 600 g potatoes
  • 400 g tinned tuna in olive oil
  • 40 g pickled gherkins
  • 30 g desalted capers
  • 3 anchovy fillets in olive oil
  • Mayonnaise or mustard, to taste
  • Salt, a pinch


Boil the potatoes in their skins until soft, then peel them and mash with a potato masher..

Drain the tuna from its oil, then break it up with your hands.

Put the chopped tuna, capers, gherkins, a pinch of salt and a little oil in a blender and blend until smooth. Add it to the mashed potatoes, add a generous spoonful of mayonnaise or mustard, mix, adjust salt if necessary.

Take the mixture and shape it like a fish with your hands, creating it directly on the serving plate.

With a rounded knife or a teaspoon, draw the scales. You can also use thin slices of radish or strips of carrot to create a clown fish.

Place an olive or caper to make the eye.

Place the Mock Fish in the refrigerator for a few hours to get firm.

Serve it cold.
