Gas stove

A gas stove is a stove that is fuelled by combustible gas such as syngas, natural gas, propane, butane, liquefied petroleum gas or other flammable gas. Before the advent of gas, cooking stoves relied on solid fuels such as coal or wood.
Gas stoves became more wieldy when the oven was integrated into the base and the size was reduced to better fit in with the rest of the kitchen furniture. By the 1910s, producers started to enamel their gas stoves for easier cleaning. Ignition of the gas was originally by match and this was followed by the more convenient pilot light. This had the disadvantage of continually consuming gas. The oven still needed to be lit by match and accidentally turning on the gas without igniting it could lead to an explosion. To prevent these types of accidents, oven manufacturers developed and installed a safety valve called a flame failure device for gas hobs (cooktops) and ovens. Most modern gas stoves have electronic ignition, automatic timers for the oven and extractor hoods to remove fumes.
Multicooker
A multicooker (also written "multi cooker") is an electric kitchen appliance for automated cooking using a timer. A typical multicooker is able to boil, simmer, bake, fry, deep fry, grill roast, stew, steam and brown food.
The device is operated by placing ingredients inside, selecting the corresponding program, and leaving the multicooker to cook according to the program, typically without any need for further user intervention. Some multicookers have an adjustable thermostat.
In addition to cooking programs, a multicooker may have functions to keep food warm, reheat it or to cook it at a later time. Some multicookers can also function as slow cookers.
Modern cookers include electronic time, temperature and pressure controllers and are marketed as "automated multipurpose cooking appliances". The most modern ones include Bluetooth and WiFi capabilities and cooking procedures in recipe scripts, mainly by choosing the temperature, time and pressure in multiple steps, to execute and share.
At the same time, the European market had been producing kitchen appliances with individual functions, such as electric kettles, pressure cookers, bread makers, toasters, steamers, microwave ovens, and yogurt makers. The multicooker combines the functions of some of these devices.
Multicookers can make hundreds of dishes characteristic of any cuisine, except those which require specific types of cooking unsupported by the appliances, such as flame grilling.
Cook (standard) – comes to a boiling point and maintains it for a predetermined amount of time. Useful for preparing soup, broth, oatmeal with milk, rice, and grains.
Pasta – heats to a boiling point and pauses with notification to the user that ingredients may be added (further automation would exclude human intervention to release ingredients). After that it comes to a boil again and maintains the temperature for a predetermined amount of time. The program can be used for cooking pasta, dumplings, eggs, sausages, and other products which need boiling water.
Fry – this setting can be used to fry meat, poultry, fish, vegetables, and seafood. Fry with an open or closed lid.
Rice/grain – heats to a boil and maintains the boil until the water is gone (via evaporation or absorption by the ingredients). This setting is used to cook boiled rice, buckwheat, peas, beans, and coarse grains.
