olla podrida (stew of seasoned meat and vegetables)
“Aquel platonazo que está más adelante vahando, me parece que es olla podrida, que por la diversidad de cosas que en las tales ollas podridas hay, no podré dejar de topar con alguna que me sea de gusto y provecho.” — That big dish that is smoking farther off, seems to me to be an olla podrida, and out of the diversity of things in such olla podridas, I can’t fail to light upon something tasty and good for me.
Inherited from Old Spanish olla podrida (literally “rotten pot”) (maybe due to the smell), or olla poderida (literally “pot [of the] mighty”) (because it was eaten by the rich), ultimately from Latin ōlla (“pot, jar”) and putridus (“decayed, rotten”) or a derivative of adjective potis (“able, capable”). Compare pudrir (“to rot, to decay”) and poder (“to be able”).
