Pomanders were originally metal or ivory filigree balls filled with spices fixed with ambergris, hence the name (from the French "pomme d'ambre", or apple of ambergris). Having a bowl of these fragrant oranges (or lemons) near an entryway or on a kitchen table is one of my favorite and easiest holiday decorating traditions. Prep time depends on how the size of the fruit; the smaller, the quicker it will harden and dry. P.S. - don't eat 'em - they're just for fragrance!
