Originally a Scandinavian dish, it is a perfect substitute for smoked salmon and costs much less when you make it yourself. Its subtle, sensuous taste is perfect for appetizers and hors-d'oeuvre as well as an excellent first course served with a salad. Once the herbs are scraped off the salmon, it will keep in the marinade for 10 days. Be sure to use fresh dill when making this, not dried. Cooking time is time required to marinate salmon in refrigerator.
