From Denmark ("Viking gryde") This stew was created by chef Dix in 1961, at restaurant "Viking Bøfhus" (Viking Steakhouse) in Århus, Denmark. The restaurant no longer exists, but the stew remains a classic among those who ever tried it.
I found the recipe at http://www.wayne.dk and it seems (tastes) authentic. I took the liberty of translating it into English and modify it into 1) a smaller portion and 2) US/English measures.
Don't be affraid of the whisky, however if you prefer or don't have it on hand, omit it.
I don't really think there's a good alternative to tenderloin since the juiciness and tenderness of the meat is very important.
Serve with oven roasted potatoes or rice, and garlic bread.
