As a cook I find that poached leeks with a simple vinaigrette makes a very satisfying first course, but for many of our customers they are just not glamorous. We have found a way to sex them up (the leeks, not the customers). We poach the leeks and then grill them to give them a slightly smoky flavor. Then we dress the grilled leeks with a walnut cream and top them with chopped walnuts. You may add chopped parsley or mint as a garnish and color accent.
