Open a hot pot restaurant, the current trend is very good, hot pot has become a catering category TOP 1, which is very suitable for inexperienced novices to do, but your problem is logically a big problem.
1. At present, hot pot has been industrialized, and basically no one is still cooking alone. Only a few well-known brands still retain the skills of cooking, and most brands in the market are basically not still cooking.
2. If you attend the so-called training, it is useless to say that it is more responsible. On the one hand, even if you complete the training, the materials you fry can't compete with the hot pot restaurants on the market now (don't doubt this). Another point is that your cooking materials are influenced by raw materials and techniques, which may lead to inconsistent tastes. In terms of cost, the cost of cooking is much higher than that of a mature supply chain.
Therefore, the logical mistake of your question is that when the market has formed an unbreakable supply chain, it is useless for you to learn to speculate.
For a truly skilled master, he will not teach secrets easily, and his experience and secrets will not spread to the training institutions in the market, so you can't learn any core technologies when you go to the training institutions.
