Arctic Char with Spinach Butter
Darina Allen, known as the Julia Child of Ireland, has run the Ballymaloe Cooking School on an organic farm in east Cork for more than 30 years. Here’s a lovely dish from her repertoire, a whole fish wrapped in a foil package, seasoned with nothing more than salt, pepper, butter and a sprig of tarragon. The fish emerges moist and juicy, ready for a creamy butter sauce packed with chopped spinach and herbs. Ms. Allen makes it with pink trout, which are plentiful in Ireland, but this recipe calls for Arctic char, which is more widely available in the United States. But you could substitute pink trout (also called coho trout) if you can find it, or large wild trout, or even thick fillets of steelhead trout or salmon.
