Do you clean out the inside of a portobello mushroom?

Chef's answer
Thankfully, removing them is pretty simple. Most recipes that call for mushrooms don't require that you remove the gills on the underside of the caps. Portobello mushrooms, however, have particularly dark gills, which can cause any dish they're used in to turn dark and unappealing.
