Submarine chef , Im pretty sure you would need a degree or specialization to work in that feild. If not it probably worse then working in a restaurant kitchen <_<.
Think who is gonna pay you to do options 2 and 3? Where can you find a job that will even pay you well? What skills do you have to get into that part of the industry? Who is gonna be your clients?
Before you actually start to think about where you want your career to be headed , think about how you will get there, what paths to take.
Regardless of that im sure that the chances of working as a recipe tester and or solely making dishes you want ,is rarer then working 9-5 and making decent pay.
If their is anything that is close to those 2 options it would be working in television hosting cooking shows , and then you really have to think..... What are the chances of me getting a job like that?
I can tell your right now , if you wanna work with food , be prepared to work long hours , work with annoying people , and get ready to learn alot. That or open up your own business.
Allow me to remind you , that you haven´t mentioned that you have experience working in the industry , so achieving a goal where you wish to work good hours and make decent pay wont happen unless you have money to invest on yourself.
Ill say it again : If you wanna work in the industry find a job in the industry. Stating you want to work with food because you like to cook at home for yourself , friends , creating new dishes etc... doesnt mean you can/should work with food. Sure maybe you have what it takes to work in a kitchen and work with food , but you wont know until you find a job in the industry now will you?
Remember you have no work experience how can you justify to a potential client or boss that you should make decent pay , and work certain hours <_<?
I know of so many cooks not just here on cheftalk , that started out washing dishes or working from PM - AM just to get some experience in the field. Getting little sleep , attempting degrees , and probably working at places below there standards. Sure many of them now have decent jobs , and have a decent pay but that was after working years in the industry , and putting in alot of heart , soul , blood , sweat , and tears , along with never regretting their choices.
If you really want to work with food , start thinking about a career choice , a plan on how to reach your goals , and go find a job ( even if it means washing dishes or prepping salads ). You need some REAL WORLD experience.
