Traditional Onam Delicacies: Avial

Have used the traditional method  in this recipe; potatoes and tomatoes are not used in this recipe. The other traditional vegetable, Elephant Yams, is available only in frozen 'cubes', hence not used.  Did not get fresh Indian long beans, which are also traditionally used alongwith Ivy gourds/ Kovakka, a small amount of Bitter Gourds/ Kayapakka.
