Cousins in Sweden served a fish meal that B really liked! [That is a huge compliment as it's not her favorite protein.] Nic makes it without a recipe so this is a general guide. Layer a casserole with a bed of zucchini slices and add a layer cod pieces . Mix chopped flat leaf parsley (handful), softened butter (abt. 2 T), horseradish sauce (abt. 1 T) with a brick (8 oz) of cream cheese. {It is easier if the ingredients are room temperature} Cover fish with sauce and bake for about 25 minutes at about 325-350 degrees [Swedish measurements are not equivalent] Thin sauce with milk if needed. Serve with new baby potatoes baked in butter and dill and salt.
