In the past what was food cooked on?

* Open fire: This was the earliest method of cooking food, and it is still used in some cultures today. Food is placed directly over a fire, and it is cooked by the heat of the flames.

* Hot stones: Hot stones were used to cook food by placing them in a pit or wrapping them in leaves. The food would then be placed on top of the stones and covered. The heat of the stones would cook the food.

* Clay ovens: Clay ovens were used to cook food by building a fire inside the oven and then placing the food inside. The heat of the fire would circulate around the food and cook it.

* Metal pots: Metal pots were used to cook food by placing them over a fire. The heat of the fire would transfer to the pot, and it would cook the food.

* Stoves: Stoves were invented in the 18th century, and they quickly became the most popular way to cook food. Stoves use a variety of fuels, such as wood, coal, gas, and electricity.
