The so-called "old oil" in people's minds refers to the "butter pot bottom" left by diners after eating old oil hot pot, and then collected and reheated. After the butter is boiled, the food residue in it is filtered out, which is the reusable "old oil". This "old oil" should be said, first of all, to save fuel, and second, people think that the older the bottom of this oil pan, the more delicious it seems, which seems to make the hot pot more authentic and delicious. Therefore, the past has always been everyone's favorite.

In recent years, for the health and safety of the catering industry, the relevant departments have expressly stipulated that this so-called "old oil", also commonly known as "saliva oil", should not be used, but a disposable fresh old oil hot pot bottom material should be used. However, even so, many people still like Chongqing's old oil hot pot, perhaps it is a taste and taste, or a kind of thought and emotion. And I like old oil hot pot for a taste and memory. I always think it's authentic and delicious, but now I'm paying attention to hygiene and safety.

The "old oil" used by people in the past is a new "old oil pot bottom" formed by heating the butter floating on the upper layer, filtering it, and then continuing to heat it to evaporate the water. The real "old oil" should be to cook a pot of oil with various spices, seasonings and other related ingredients, and then add new spices and butter after cooking to a certain extent. This made "old oil". In this way, after repeated blending, all kinds of ingredients can give full play to their proper taste, and this old oil should be the same as the common old soup and old brine.

For this reason, like everyone else, I like Chongqing Friends Hot Pot, except that it is a traditional and famous ingredient, which may be somewhat touched by my frequent eating. Here, I hope that friends who like Chongqing old oil hot pot must also pay attention to food hygiene and safety, not only to enjoy the food, but also to pay attention to their health.
