Chinese restaurants often use propane stoves instead of electric ranges with flat tops for several reasons:
High heat output: Propane stoves can produce much higher heat levels compared to standard electric ranges. Chinese cuisine often involves quick stir-frying and wok cooking, which require intense and immediate heat to achieve the desired flavors and textures. Propane stoves can provide this high heat rapidly, allowing chefs to cook dishes quickly and efficiently.
Better control: Propane stoves offer precise flame control, making it easier for chefs to adjust the heat quickly during cooking. This level of control is essential for achieving the right balance of flavors and textures in Chinese dishes that require varying heat levels throughout the cooking process.
Energy efficiency: Propane stoves can be more energy-efficient than electric ranges, especially when used in high-demand commercial kitchens. In some cases, using propane stoves can be more cost-effective for restaurants compared to electric ranges.
Versatility: Propane stoves can accommodate a variety of cookware, including traditional woks. The round-bottomed woks used in Chinese cooking require direct flame contact for optimal performance, which is challenging to achieve on a flat electric surface.
Faster heat-up times: Propane stoves heat up quickly, allowing chefs to start cooking almost instantly. Electric ranges, particularly those with flat tops, may take more time to reach the desired temperature.
Dependence on gas availability: Some Chinese restaurants may have limited access to electricity or face higher costs for electrical usage. In such cases, using propane stoves can be a more practical option.
Tradition and familiarity: Many Chinese chefs are trained in cooking with gas stoves, especially wok cooking. The familiarity with gas stoves and the traditional methods of Chinese cooking often lead to their preference in restaurant kitchens.
It's worth noting that while propane stoves are common in many Chinese restaurants, the choice of stove can still vary based on the specific restaurant's preferences, regional cooking styles, and kitchen setup. Some Chinese restaurants may indeed use electric ranges with flat tops for certain cooking tasks, especially in more modern or Western-influenced settings.
