- Look at the salmon color: smoked salmon should have a beautiful orange pink color. If the color is too pale, it can mean that the salmon has not been smoked long enough. If the color is too dark, it may indicate that the salmon has been smoked at a too high temperature. - Feel the smell of salmon: smoked salmon should have a pleasant and slightly smoked smell. If the smell is too strong or unpleasant, it can mean that the salmon has been smoked with artificial aromas or that it has started to turn. - Tap the texture of the salmon: smoked salmon should have a firm and dense texture, without being too dry. If the salmon is too soft or too dry, it may mean that it has not been smoked correctly.
