In China, a lot of people know that the barbecue is the roadside kebab, and the barbecue really accords with the eating law of Asians, and the Asians like eating small pieces. However, in Europe and America, the barbecue is biased to large meat blocks, so the braising is a very popular barbecue mode in Europe and America, namely the braising is carried out by braising with an oven cover, which is helpful for keeping the original taste and flavor of the delicious food, and the roasted food is scorched outside and tender inside. Many traditional barbecue methods are similar to the traditional barbecue methods, and the traditional barbecue methods such as Beijing-flavored roast ducks are one of the braising methods.

The most main braising and roasting is indirect roasting, namely, food is placed in a place which is not in direct contact with flame for roasting, so that scorching is avoided.

The prior roasted products in China are mainly directly roasted by naked fire, so that the surface of the roasted products is very easy to be burnt, and the roasted products in the market tend to be roasted by stewing gradually, but the prior stewing mode avoids charcoal fire when the roasted products are stewed, so that the stewed and roasted finished products of dishes generally do not have natural flavors such as carbon fragrance and the like, and the stewing effect of the stewed and roasted dishes still has certain disappointment for domestic users who are used to charcoal fire roasting, and meanwhile, the stewing and roasting efficiency is poor because the stewing and roasting furnace is used for stewing and roasting, and the stewing and roasting effect of the next wave dish can be generally carried out after the stewing and roasting effect is sealed for a certain time.
