Step 1

Preheat the oven to 400°. Thinly slice the scallops crosswise. Spread them in 4 ovenproof soup plates. Melt the butter in a medium saucepan. Brush the scallops with some of the butter and season with salt and pepper.

Step 2

Add the mushrooms to the remaining butter in the saucepan. Season with salt and pepper and cook over moderately high heat until lightly browned, about 5 minutes. Add the leek and ginger and cook, stirring, until wilted, about 3 minutes. Add the stock and bring to a boil. Season with salt. Keep hot.

Step 3

Bake the scallops in the oven for about 30 seconds, or until the bowls are hot. Pour the hot soup over the scallops, garnish with the cilantro and serve.
