We had bought some chicken liver at the poultry stall on the market and I had a package of pie dough left in the refrigerator. With some shallots, raspberry vinegar, eggs and cream, I made a nice quiche-like open pie.
Why raspberry vinegar? It is one of those French habits. The vinegar helps to kill any bacteria that might be lurking in the innards and raspberry gives sweetness to the taste. Alternatively, balsamic vinegar or wine can be used with chicken livers.
