When ready to cook, rake the coals into an even layer using a grill hoe or garden hoe. Fan with a folded newspaper to disperse any loose ash. Lay the grill basket with the peas directly on the embers. Grill the peas, stirring occasionally with tongs, until browned and charred in places, about 5 minutes. (A few burnt spots add flavor.) Transfer the peas to a platter and serve.
Note: If you own a gas grill, try charring them on a plancha or grilling basket.
