My own recipe. One can use beef instead, but then it's more a 'hunter's beef'.
Ingredients: Butter, potatoes, onion, whale beef (I had to use some lard too since I ran out of butter)
In a greased pot, peeled and sliced but not rinsed potatoes. On top of that, fried onion, beef boullion powder, 1 tsp flour, bay leaf, thyme and juniper.
The meat is quickly seared on high heat, sliced and put on top. Quite a lot of salt and pepper too.
Another layer of potato slices and half a litre of beer is added. Some butter on top, brought to a boil on the stove and everything is baked, uncovered, in a 225 C oven for 45 minutes until some of the liquid has evaporated and the potatoes are browned. Served with chopped chives on top. Worcestershire sauce on the table.
