This recipe has potential. The balsamic glaze was tasty on the salmon, but we thought the fish needed more flavor. If I made this again I would substitute spinach for the watercress, which was too tough and bitter for our taste.
Delicious and fast! I added caramelized onions to the vinegar mixture before reducing; timed the salmon exactly as listed and it came out incredibly moist, perfectly sweet and tangy. Next time I will chop the watercress before adding to the vinegar mixture so that it is a little less splattery when picking it up from the dinner plate.
