For the most intense smoky flavor and deepest gold color, use a charcoal barbecue. To present smoked trout as an appetizer, serve on thin triangles of Westphalian-style pumpernickel bread with sour cream, chopped red onion, and lemon wedges. For a salad, combine chunks of smoked trout, hot or cold, with green salad mix and a vinaigrette dressing. As a main dish, serve trout hot with boiled small thin-skinned potatoes, melted butter, and lemon wedges. Chill smoked trout airtight up to 1 week or freeze up to 1 month.
