Blend It, Poach It, Pack It, Sear It
Cooking in parchment (essentially steaming in a tightly sealed package in the oven) is a favorite French approach, especially for fish. It also makes for a beautiful presentation. Slice hard ingredients, such as fennel and potatoes, very thin so they cook in the same time as the more delicate seafood. Don't have parchment paper on hand? A sheet of aluminum foil works just as well.
