“What was he cooking?” meme originated from a scene in the animated film, “Ratatouille,” where the character Remy, a rat, is watching a human chef cook. The scene became a popular meme format, with people adding their own captions to the image of Remy, typically expressing surprise or confusion about what the chef is cooking.
The meme has been used in a variety of contexts, often to express disbelief or amusement at someone’s actions or words. It has also been used to poke fun at people who are overly serious or pretentious. The meme has become so popular that it has even been featured in other works of popular culture, such as the TV show “The Simpsons.”
