Plaster of Paris powder is very light and fine, so wear a dust mask while mixing to avoid breathing it in. It also hardens quickly, so do not dispose of it in a sink, drain, or toilet, where it can cause clogs. Instead, let it dry in the mixing container, tap to loosen the edges, and empty into the garbage. To remove plaster from mixing utensils, scrape off hardened plaster, wipe with a damp cloth, and wash as usual. Once hardened, arrange the artificial fruit on an equally pretty vessel. We used a gold tray, but the brilliant thing about this tableau is that it looks good with any palette or décor. Another idea: Set individual pears or apples at each place setting on your holiday table.
