Food Palate Map

I think the palate is perfect example of an intensive surface.  The palate is composed of five main assemblages (sweet, salty, sour, bitter, umami).  All food is but a combination of these five attributes in the same way that a sound is a combination of frequencies.  The palate has sensitivities to certain tastes and sends this information up to the brain where it is translated emotionally (e.g. "Mmm, this pretzel is good and salty" or "This coffee is impotably bitter.").
