I once had a coffee maker given to me, I think it was called the Toddy coffee maker, but I am not totally sure. That gizmo made the best coffee ever.And I love drinking coffee....you put a pound of ground coffee in the container, added a specified amount of cold water and let it set for a certain time. the result was a syrup like black concentrate. all you did was add a spoon ful to a cup of hot water. I kept it in a jug in the fridge, but my friend froze it and used a cube for a cup. the cold water leached out all the good flavors and left all the acid in. It was so much more mellow and flavorful.
