Often mistaken to be, sounding-alike, as kinchay, kusay has a very distinct aroma and flavour. A rather unfamiliar herb mostly anywhere, my Tagalog officemate call this as sibuyas na mura and in Manila groceries labeled as kutchay. 
It do looks like onion chives but kusay is flat unlike the hollow chives. We have kusay planted in our backyard for occasional uses like soup garnishing.
However, it often takes a trip to the Central Market to buy them in large quantities if ever we make Pancit Molo since it is an important ingredient in the filling mixture and as garnishing.
