An alternative preparation for salmon is as follows.

Place salmon, fillet or steak, on a large sheet of foil. Pour over some
liquid (amount not critical, you are aiming to steam the fish not give it
post mortal swimming lessons), a dry white wine would be excellent. Add
fresh herbs of your choice - Parsley or tarragon perhaps. Add some spring
onions (scallions for those of you on the left hand side of the Atlantic)
and season well.

Fold the foil up and seal the fish in. Leave enough space in the parcel for
the liquid to steam.

Place parcel on the top shelf of your dish washer and run it at a normal
heat setting. Perhaps best not to add detergent!!

Result - one perfectly steamed salmon.
