The Silk Robe refers to the silky texture leeks, fennel, and carrots take on when cooked slowly. You can grill the salmon, or roast it high or low temperature as you wish, or cook it entirely in a pan on the stovetop. Each method gives a different but delicious result. Higher temps yield a crispy part of the fish, where a slow and low cooking results in a supple and silky fish that matches the vegetable topping. Pan searing gives a crisp top deck and low oven heat yields silky flesh to meld with the topping. Because there are so few ingredients here, and cooking is so simple, be sure to use only the best ingredients. You could use halibut or other thick bodied flaky fish for this recipe, or even slowly poached chicken.
