Cod liver and roe pâté is a delicate, healthy, and popular delicacy, rich in Omega-3 fatty acids and vitamins A, D, and E. It can be purchased ready-made or made at home using canned cod liver and roe, mixed with hard-boiled eggs, onions, mayonnaise, herbs, or spices, creating a mousse-like texture for sandwiches, croutons, or fillings.
