In olden times, before there were gas and electric stoves and Filipinos cooked over burning wood or charcoal, the palayok, or clay pot, was a standard cooking vessel.
Today, many restaurants with Filipino themes, decor and menu serve soups and stews in palayok but, from the looks of the palayok, often new and without the telltale signs of the bottom having been exposed to heat, it would appear that the food was cooked in some other pot and merely poured into a palayok for that rustic and “authentic Filipino” touch.
The palayok, in other words, has become ornamental. In the city, at least. Are they still used in rural areas? Considering that in some parts of the Philippines, there is still no electricity, I guess so.
