Mackerel Fillet

A pelagic fish bursting with Omega-3 fatty acids (highly prone to oxidation). Its strong metallic and oily flavor demands a powerful acidic counterpoint. Gastronomy often approaches it through the chemistry of escabeche or cold marinades (lemon juice, vinegar). This acidic shock instantly "cooks" the thin outer layer by denaturing proteins, while the inside remains raw and silky. Expressly charred with a blowtorch, its thin, bluish skin develops incomparable pyrazinic notes of grilled fish.
