Once, the Maharaja of Travancore ordered a grand dinner in his palace. In the afternoon before the dinner, the Maharaja entered the kitchen to survey the dishes that had been prepared for the feast. He saw vegetable scraps lying in a basket and asked the cook not to throw it away but utilize them. The cook thought about it and came up with an idea.
The cook served this new dish to the guests that evening.
It smelled very good. Everyone was eager to know the name of the new dish. The cook named it avial (uh-vi-ul).
Avial became famous all over Kerala and is now one of the dishes in a traditional Kerala feast.
