Egg Coffee is a Scandinavian thing... it is Church Basement Coffee.
Egg Coffee
Boil 9 cups of water in a coffee pot on top of the stove. In a bowl mix an entire egg (Yes you can use the shell too if you wish) into 3/4 cup of coffee grounds with 1/4 cup of water. Drop the egg and coffee mixture into the pot and let is simmer a bit then add a cup of cold water to help settle the grounds a bit, use a coffee strainer to strain into a cup and enjoy!
Most likely the best coffee ever! Our neighbor Arvilla made egg coffee all the time.
