  10. Bring the top and bottom aluminum foil over the salmon and fold a few times. Then bring the sides together and fold a few times to make sure the foil is tightly closed and no opening. Repeat the same process for the second salmon.

  11. Place the two sets of salmon in foil on a frying pan and cover with a lid (no need to add water). Cook the salmon over medium heat for 2 minutes, then medium-low heat for 10 minutes. Alternatively, you can bake at preheated 400 ºF (200 ºC) oven for 12-15 minutes.
