Note: To make Green Onion Brushes, select large green onions. Cut off root ends, leaving as much white part as possible. Cut onions in 3-inch lengths. Place on board and using sharp knife, make slashes lengthwise from each end, cutting 1/2 inch toward center. Place in bowl of cold water and onions will open up and curl back. Chill in water 1 hour or overnight. Drain well before using.
