Nothing could be simpler than wrapping everything in baking paper and popping it in the oven! Cooking en papillote is a simple yet elegant method that allows fish to steam in its own juices and those of the vegetables. Here, we use baking paper rather than aluminium foil – a technique that is equally suited to family meals and dinners with friends. Each guest receives their own small, fragrant parcel, which they can open at the table to release the aromas: a real treat for the senses. The vegetables can be varied according to your tastes or the season, making this recipe both practical and versatile.
