I can remember going to the food store (Torley's in Pomona, California) with my folks and they bought a wax paper bucket of peanut butter. They bought it at the butcher's counter. The butcher scooped the peanut butter out of a barrel and filled the paper bucket. Waxed paper buckets were used for various food items and were in common use. The bucket was square and had a wire handle. By the time we got home the peanut oil was seeping through the waxed paper bucket. You could see a line halfway up the bucket that marked the seeping oil. The peanut butter had to be transferred into a glass container.
I liked the peanut butter. Over the years I have learned to like it much more. I have eaten a barrel or two of peanut butter in my lifetime. 95 years. That is a lot of peanut butter! And jelly, jam, or honey.
