Mix 2 cups water with 2 tbsp. white vinegar and simmer on low heat as you cook the salmon. The vinegar will naturally absorb the fish odor and prevent it from lingering through the home.
Place a few bowls of either vinegar or baking soda around the kitchen, or place one or two bowls of each. Both work as natural odor absorbents.
Simmer a homemade freshener on the stove. Mix about 2 cups water, 2 sticks cinnamon or 2 tbsp. cinnamon, and 4 cloves in a pot. This emits a fresh, clean smell throughout the kitchen and masks the salmon odor.
Remember to open windows or turn on your stove hood when cooking so the fish scent can air out.
