Which is correct "The yolk of the egg is white" or "The egg yolk is white?"

Why this works

This riddle plays on the expectation of grammar and color. At first glance, the phrases seem to set up a comparison between two grammatically correct statements, leading the listener to think about the structure rather than the content. However, the twist is that both statements are technically incorrect because egg yolks are actually yellow, not white. It cleverly tricks you into focusing on language when the real answer lies in the biological fact about egg yolks!
