Starters in kitchen

It may help you to take some classes - they can be amateur level classes at a local culinary school or the culinary program at a community college.  I am not suggesting you go into debt taking a culinary program that graduates you in 6 or 8 or 10 months; but take some classes on specific things (e.g., pastry, cake, bread, entremet).   The lesson will help you to learn why something is done the way it is in the environment of a classroom and not a production kitchen, and to be able to ask questions in a learning environment.

When someone is starting out in a kitchen with no prior experience, it means that the manager or senior staff need to take this person under their wing and explain everything; and in many cases, this isn't possible.  I have seen firsthand that managers hire novices and they don't do enough to train them because they need a pair of hands in the kitchen and throw you in the deep end of the water, so to speak.  You don't know enough to swim and you ask questions and no one answers them but you're expected to absorb the way things are being done and do them identically.  Sometimes it's just the way things are and it is in no way a reflection on you.  But there are things you can do to help yourself.  Learn to observe, and know that even the smallest detail can mean the difference between success and failure.   For example, today I had someone dipping cheesecake pops in melted chocolate.  They did a messy job because they weren't paying attention - they dipped too deep and got chocolate above the ball and on the stick, which looks sloppy to a customer.  They didn't shake off enough excess and that caused a foot to form when they were placed down.  They didn't think they were doing anything incorrectly but it's those little things that matter to the finished product. 
 

I believe they may be telling you either you are careless or  not paying attention to detail. This could be because you are really not interested or find  job boring. In particular in pastry and baking you must follow recipe and get details correctly.
