I make Erissery in two ways, one with Mathanga and Karamani, which is a form of kuttan, and Chenai vazhakkai Erissery which is a thick variety, a side dish. The one I have prepared here is a thick side dish. Here i have used the normal vazhakkai, but the traditional method is by using nendram kai/ Kerala banana.
