Palayok is a Tagalog word; in other parts of the country, especially in the Visayas, it is called a kulon; smaller-sized pots are referred to as anglit.
It is instead cleaned by soaking in warm water and when the detritus has sufficiently softened, by scrubbing with salt.
[1] Filipino cuisine expert Maria Orosa is credited with turning the earthenware pot into an oven.
Called the "Palayok Oven",[2][3] the contraption consists of a palayok fitted with a piece of thin sheet metal cut to fit the bottom of the pot and a piece of aluminum foil placed below the lid.
The pot is heated by using a native pugon or kalan, a small wood-fired stove similar to a Japanese shichirin.
