Dave Drum's points about Gravlax being Scandinavian thereby having little connection to chile-hot in its native form does not preclude adding a little to the spice mix. Dave's recipe using lemon grass looks good, but uses no chile. You could substitute some of a favorite powder (dried red ancho, or cayenne or habanero) for some of the black pepper and get the effect. Salmon marinating in dill, lemon and garlic is a good preparation for the grill. When I know the missus is not looking, some dried ancho powder goes in and no one complains, not even the cat. Such an addition will blend nicely. It is interesting Dave's recipe uses gin, but Dave uses vodka. The Swedes would certainly use Akvavit (think Absolut Vodka), but it could be flavored somehow, especially if it were home-made. The flavor might even include juniper berries. George Nelson
