Morels are a traditional delicacy here in Finland. Or, to be precise, false morels (Gyromitra esculenta) are. They are much like the morels found in the US except they are highly poisonous if not prepared correctly (boiled twice in ample water, changing the water between the boilings, taking care of good ventilation at all times). False morels can justifiably be called the the fugu of the mushroom world.
But that aside, they taste fantastic. One traditional Finnish recipe is to sauteé them with chopped onions and add a little double cream to make a very thick sauce. If you like herbs, tarragon is excellent with morels. The sauce is fantastic with steak and even better with fish (grilled salmon or gravlax are just out of this world with a thick morel sauce).
Cheers,

PS. Naturally, we take some offense in the terminology. We call Gyromitra esculenta the real morels and the non-toxic ones false morels ;-)
