Prep Halibut Like A Chef

Mastering Flatfish Anatomy

Prepping a large flatfish like halibut demands a blend of confidence, anatomical knowledge, and meticulous knife work. In this demonstration from the Fallow kitchen, the focus is on extracting maximum yield from this prized premium species. Unlike round fish, flatfish present a unique skeletal structure that offers four distinct fillets. Mastering this breakdown requires understanding how to navigate the central spine and lateral lines to ensure clean, high-yield cuts that respect the ingredient and preserve the integrity of the flesh.

The Art of the Four Fillets

The filleting process begins with stabilizing the fish on a clean, spacious board. Using a sharp, flexible filleting knife, the chef locates the natural seam running down the centre of the fish. By slicing down to the backbone and working the blade outwards at a shallow angle, you can cleanly peel the meat away from the rib cage. This process is repeated on both the dark top side and the pale underside, yielding four flawless portions. A steady, sawing motion with a flexible blade is then employed to skin each fillet, leaving behind zero wastage and pristine, smooth surfaces ready for portioning.

Maximising Yield and Waste Reduction

In line with Fallow’s nose-to-tail culinary philosophy, the prep work does not stop at the fillets. The frame, head, and collars represent significant value in a professional kitchen. The gelatinous bones are ideal for clarifying into premium stocks, dashi, or bases for rich sauces. The collars can be grilled over open fire, while the cheeks offer a tender delicacy. By utilizing the entire fish, chefs can significantly improve food costs while showcasing sustainable practices on their menus.
