Rainbow trout is one of my absolute favourite fish—it’s mild, delicate, and packed with flavour, without needing heavy seasoning or sauces to shine. Unlike other fish, it doesn’t need to be overpowered with lemony marinades. Instead, it pairs beautifully with herbs, butter, garlic, spices, and creamy or smoky accompaniments.
