BUT, it is the smoothest way to enjoy a cup of coffee.
This is s scandinavian tradition.
After you get over the shock, try it!
You will need to use a stove top coffee pot, a clear pyrex coffee pot is best.
You will add the coffee mixture directly into the water.
Return to a boil. Remove from heat and add a "shot" of cold water to settle the grounds. If you brew it correctly, you should see a "foxtail red" colored coffee.
