Cut halibut into four even pieces. Remove the peel from the asparagus spears and cut them into diagonal slices. Sauté briefly in a frying pan with a little butter, salt and sugar. Lay out a parchment paper about
40 x 40 cm. Form the asparagus spears in the center, place the halibut on top and season with salt & pepper. Cut the tomatoes into quarters and spread them evenly on the halibut. Pluck a few tarragon leaves and place them on the halibut. Brush the edges with egg white and fold the parchment. Put in the oven at 180 degrees ° for about 10 min.
When the parchment turns slightly brown on the top, the fish is cooked. Next, bring to the table on the spot. As a side dish, potatoes are best.
