Rose, thanks for sharing your experience with the ‘portable soup’ recipe. I had never heard of it and love the idea!
Leigh, thanks for explaining about gelatine. I never thought of making it at home. I thought it came from hooves.
I remember reading several years ago about a product that the pioneers on wagon trains carried with them that was the forerunner of the bullion cubes. I tried to find what it was called and found it here:
The biscuits resembled a light colored cake and were packed in airtight casks or tin cannisters. Both meat biscuits and portable soup were forerunners of today's bouillon cube.
It was the Meat Biscuits. I bet they were some sort of dehydrated product.
Thanks again for the interesting topic.
