Nonpeareil

A side-effect of spending many hours of my youth in a hot & sticky orchard is that I've nearly exhausted all possible fruit puns. However, since I spent more time in the peaches than the pears, I appearantly neglected a few choice pear puns (not to be confused with bare buns). Like nonpeareil -- which perfectly describes today's challenge. How can I take something as unparalleled as a ripe pear, and tamper with it? The fact that my pears are quickly morphing from exquisitely ripe to brown mush is, of course, the only reason I would tamper with them.
