Overview

Lake trout (Salvelinus namaycush) is a freshwater char native to the cold, deep lakes of northern North America. It is the largest species in the char genus, with a record weight exceeding 100 pounds. Its flesh is firm, flaky, and rich in oil, with a flavor that ranges from mild to pronounced depending on the fish’s fat content and diet.

Origin and history

Lake trout are endemic to the northern United States and Canada, with a range extending from the Great Lakes to the Arctic. They have been a traditional food source for Indigenous peoples of the region for centuries. Commercial fishing for lake trout in the Great Lakes peaked in the late 19th and early 20th centuries. Populations declined significantly in the mid-20th century due to overfishing, habitat loss, and the introduction of the parasitic sea lamprey. Restoration efforts have since recovered some stocks.

Varieties and aliases

  • Mackinaw
  • Lake char (or charr)
  • Touladi
  • Togue
  • Grey trout
  • Siscowet (a fat-rich morphotype found in Lake Superior)
  • Paperbelly (a lean morphotype)
  • Lean (a lean morphotype)

Culinary uses

Lake trout is commonly prepared by smoking, grilling, baking, or pan-frying. Its high oil content makes it well suited to smoking, which is a traditional preparation across the Great Lakes region. The flesh can be poached or used in chowders. It pairs well with acidic accompaniments such as lemon, vinegar, or pickled vegetables, which cut through the richness. The siscowet morphotype, with its exceptionally high fat content, is especially prized for smoking.

Cross-cuisine context

Lake trout has no direct analogue in Mexican cuisine, where freshwater fish preparations tend to use species such as tilapia, trout (rainbow trout, Oncorhynchus mykiss), or charales (small silversides). In terms of fat content and cooking method, lake trout is closest to salmon or Arctic char, both of which are also commonly smoked. Lake trout is not a traditional ingredient in Mexican-American cuisine and is rarely marketed in Los Angeles; it is seldom used by regional chefs. In Korean and Japanese cuisines, lake trout is not a traditional ingredient, though its fatty flesh could be grilled or used in stew-like preparations.

Notes for cooks

  • Lake trout is highly perishable and should be kept cold or frozen immediately after catch or purchase.
  • The siscowet morphotype is significantly oilier than the lean morphotype; adjust cooking time and fat content of accompaniments accordingly.
  • Overcooking can dry out the flesh despite its high oil content. Cook until the flesh is opaque and flakes easily with a fork.
