Anything is good if it's made of chocolate.

In its comic exaggeration, the line treats chocolate as a universal solvent for dislike: whatever the object, the addition of chocolate makes it desirable. The humor depends on a knowingly “unreasonable” absolutism that mirrors everyday indulgence—how cravings and comfort foods can override judgment, taste, or even common sense. Read more broadly, it pokes fun at consumer culture’s tendency to improve anything by adding a beloved flavor, and at the way pleasure can become a simple, reliable criterion for “good.” As a Jo Brand quip, it also fits her persona of blunt, wry observation about appetites and ordinary life.
