1940's or earlier short

In the 1950's I used to see an amusing short film on TV from time to time. As I recall, there is an unseen narrator moving through a house, questioning various party goers about some secret or mystery. In the end the secret is merely a recipe. That's my best recollection of this short film. As a young child I found it quite funny and was always pleased when I watched it on TV. I've searched the Internet and, many years ago, the IMDB forum trying to track it down. Does anyone have an idea about this? I've been thinking about it for many, many years without finding anything . . .
