"Gourmet," maybe. Or "epicure." But not gourmand. A gourmand is supposed to have an utterly undiscriminating appetite; he'll eat anything, any time, with gusto but no palate, no appreciation whatsoever of any finer sensibilities.

(Noodling about, I see the distinction is becoming blurred with time, and the original gluttony/piggishness of "gourmand" is being lost. The prescriptivist in me rebels. But then, I also think that "disinterested" and "uninterested" don't mean the same thing, which is disputed as far back as Webster's Third International Dictionary. And that's back in 1961.)

Who you gonna believe, me or some strange dictionary?
