Why This Recipe Works

In this beautifully simple yet elegant skillet dinner, meaty cod poaches in white wine on a bed of potatoes and onions with green beans steaming on top. To ensure all the components finished at the same time, we staggered their cooking: The sliced potatoes and onions went in first, followed by the cod and then the green beans. To even out the thickness of the pieces of cod for even cooking, we folded their thinner tail sections under. A couple tablespoons of butter scattered over the fish added richness, and briny preserved lemon brought depth.
