After investigating that quote, so far I’m led to one Count Peter Ludwig von der Pahlen, who was involved in the assassination of Czar Paul of Russia back in 1801. May turn out to be someone else, but that’s what I got so far.
The use of the word “omelette“ would indicate an upper class person. A lower class person would have used the words “scrambled eggs“. So, your attribution to a Count sounds accurate.
