Use a food processor and blend together the bacon, mushrooms, and onions until very fine. Practically a paste.
Melt the butter in a saucepan. Take off the heat and add the cream to cool it down.
Add the liver to the food processor and then add the butter/cream mixture.
Add remaining ingredients (beef bouillon, eggs, anchovy paste, flour, etc) and spices.
Pour into small aluminum baking dishes and top with a slice of bacon. This is extra bacon that you have from the pack.
Bake at 360 degrees for about an hour using a water bath. (put aluminum pans into a bigger baking dish and add some water to the bottom)
Enjoy with toast or rugbrød topped with some dilly beans or asier (danish pickles).
