A paniyaram pan (appakarai, appakaram) is a stove-top pan that has somewhat the functionality of a muffin tin.
It resembles a kanom krok pan in Thailand, and an aebleskiver pan in Denmark, or a frying pan with a permanent egg-poaching insert in it with rounded cups in it.
It is used in India for making kuzhi appam.
