Ovens can be bought in wholesale markets or online. There are all kinds of ovens, and the one that suits you is the best.
Barbecue raw materials are basically bought in the local wholesale market and can be bought at one time. Such as chicken wings, mutton kebabs, vegetables, and so on. And brushes, some barbecue materials and so on.
As for the barbecue recipe, no one will make it public. So there are skills here, one is to find someone to learn, the other is to find ready-made ingredients to cook. The barbecue made of good barbecue ingredients tastes good and the business is good. Here, I recommend a shop to buy ingredients for you. It used to be a factory specializing in the supply of crazy roasted wings and roasted wings. They have a shop on Taobao. Which store do you want is called "barbecue kitchen" and Want Want is called "crocodile nails". It's called pickling and sprinkling, which can basically meet your requirements. There are big bags and small bags. You can buy a small bag to taste it in the early stage, and at the same time you can practice how to do it and get familiar with it.
Let me remind you that it must be cooked when baking. This can only be done by practicing more hands.
I hope the landlord's business is booming.
