💡 Chef's Insight
Buffalo is a native fish with a real commercial and cultural history in the Mississippi valley, and it is nothing like the carp it gets confused with. The challenge is bones, and there are two proven answers. First, scoring: cut the fillets crosswise every eighth of an inch down to the skin, dredge in seasoned cornmeal, and deep-fry hot — the fine bones fry to nothing and you eat the fillet whole and crisp. Second, smoke: brine thick pieces overnight in salt, brown sugar, and pepper, then hot smoke over hickory for four hours until the flesh burnishes and flakes. Smoked buffalo, flaked and folded with cream cheese, lemon, dill, and capers, is the equal of any smoked fish dip on either coast.
Safety Context
Moderate concern, weighted toward large, old fish from industrial river reaches. Skinning and trimming fat is important. A reasonable occasional choice for adults from cleaner waters; check local river advisories.
Primary Contaminants
PCBs and mercury from sediment and plankton feeding in large river systems. Extremely long-lived — documented past a century — which raises accumulation in old fish.
