Green peppercorns are the same as black peppercorns, in that they are picked when green and unripe. But instead of being dried in the sun, they are quickly dehydrated so that they retain their bright green colour and mildly spicy flavour.
Green peppercorns are also packed fresh in brine to preserve them without drying. We carry Moulin Poivre Vert canned green peppercorns. The Moulin family of France hand-selects and sorts Madagascar-grown green peppercorns, preserves them in saltwater brine, and then packs them in a distinctive green, black and white can. These soft green peppercorns are common in French cooking, and are most famously used in steak au poivre.
