José María prepares this dish with liver from a recently slaughtered suckling pig. However, the strong flavour means that the other ingredients can easily be overlooked by diners so, if possible, use mushrooms to balance the flavours.
Sauté the pork liver in a little olive oil and set aside. Sauté the mushrooms and garlic in 2 tbsp olive oil until tender. Add the liver and heat through.
Create a mound of the liver and mushrooms on a serving plate, splash with the vinegar, garnish with the pine nuts and serve immediately.
