Please tell me in detail how to keep mutton kebabs fresh. Thank you.

You can put it in a fresh-keeping bag, squeeze the gravy hard and squeeze the air out of the bag to seal it, but you should eat it in a short time. If there is a frozen layer, you can also put the amount of each meal into a fresh-keeping bag and put it into the frozen layer, and the taste is the same.

Barbecue is probably the most primitive way of cooking. It uses fuel to heat dry air, and puts food in dry and hot air near the heat source to heat food. Generally speaking, barbecue is to cook food (mostly meat) on a fire until it is edible, so it is also called barbecue in Taiwan Province Province. In modern society, because there are many ways to use fire, the barbecue methods are gradually diversified, and various barbecue ovens, grills, barbecue sauce and so on have been developed. Barbecue itself has also become a way for many people to get together for entertainment or business. Barbecue alone is rarely seen in modern society. No matter in Asia, America and Europe, barbecue is usually a group activity from home to school.
