Thrift store stop on the way to the office. (The red slash means 50% off.) Hostess casseroles/serving bowls and ramekins were sold from 1949 to 1953. These 407s are the smaller of the two sizes of ramekins. Their condition is remarkable for being over six decades old.
I always look forward to your posts, Doug. Can you tell me what ramekins were used for and where the name came from? I have never seen one in the wild. Thanks. Dave
The term is not proprietary to Pyrex. Basically just small individual serving dishes. Google can define it more comprehensively for you than I.
