Trout is a favourite fish with anglers. There are many types of trout found around the globe. Rainbow trout is a fish native to the USA and is popular with fish farmers because it is relatively easy to breed. Steelhead trout - a sea-going rainbow trout - is also found in the USA. Brown trout is native to the British Isles and is organically farmed, making it readily available. Trout can have an earthy flavour, particularly if caught in the wild, and therefore benefits from citrus and acidic flavours including lemon and capers.
