Tvøst og spik (also called Grind og spik) is a typical dish of the Faroe Islands, a self-governing country of Denmark in the North Atlantic.
Tvøst og spik consists of pilot whale meat, blubber and potatoes.
The meat is prepared in different ways, it can be boiled or fried fresh, it can be stored in either dry salt (turrsaltað) or in very salty brine (lakasaltað),[1] it can be frozen and later prepared, or it can be hung up outdoors to dry, then cut in long slices (grindalikkja) and hung under a roof away from the rain.
The blubber can also be prepared in different ways, boiled, salted or dried, but not fried.
Faroese culinary traditions thus evolved to make heavy use of animal products from households, such sheep, cows, geese, chicken and ducks, and maritime produce, from all kinds of fish and sea birds to, from time to time, whale meat and blubber.
