Remove the skin from the cucumber, cut in half lengthwise and scrape out the seeds with a soup spoon. Cut cucumber halves diagonally into slices and stand lightly salted for 1 hour. Drain and cook in a small saucepan in the whipping cream over medium heat for 8 minutes.
Heat white wine, bay spice and salt in a shallow saucepan and poach cod chops in it for 8-10 min. Add mustard and tarragon to cucumber form, stir well and heat. If the sauce is too thick, add a little fish stock. Serve cod with cucumber sauce. Serve with new potatoes.
