Hi Doak , Here in Canada the grocery stores sell a product which I believe you may find comparable to Postum It is called "Caf-Lib" . This year we had a bumper crop of beets in the garden . My wife and I decided to try making our own coffee substitute By shredding and roasting it on cookie trays lined with bakers parchment paper at 375 d. F. in the oven . To that we added roasted pot barley ( the kind used for adding to soup ), and roasted wheat , all in equal parts . Everything was roasted till it was coffee brown colored . Then it was ground 2 handfuls at a time in the blender . We make it in our automatic drip coffemaker just like we would make regular coffee . Sure its a lot of work , but its wintertime and my spouse and I enjoy having a project like this that we can do together . :) . We call the beverage "BWEET" . Susan says to tell you " We quite like it ! " It has a pleasant flavor and is soothing to the stomache . Hope this helps .
On another note , do you suppose that when Moses came down Mt. Sinai with the stone tablets which contained the 10 commandments and found the Isrealites worshipping a golden idol ; Do you think maybe that was the first ever recorded need for "de-calf-a-nation" ? :-D
---Burl--- If your coffee tastes like mud , perhaps it's because it was fresh ground this morning .
