Avial is a thick, mixed vegetable dish in which the vegetables are chopped and parboiled, flavoured with yogurt, and then cooked in coconut milk (you can use any combination of vegetables). The avial also forms part of a vegetarian feast in Kerala known as the “sadya”. The method of serving a sadya is very precise. Only after all 11 or so dishes- pickles, stews, lentils, and other delicately spiced curries and rice- are placed on a banana leaf does the person begin eating.
