Editors of gastronomic publications want candidates with experience in writing gastronomic stories, so it is essential to create a portfolio of published work. So, gain experience in the food industry in any way you can. A job at a farm or grocery store may not seem like it has much to do with writing about food, but by enriching your base of experience, you gain a real world experience that you can relate to and that, if nothing else, will give you something to write about. If you want to write about restaurants, for example, it never hurts to work on them first.
If you think you want to develop recipes, get a hands-on dining experience in a kitchen. It's 11 o'clock, what snack are you looking for? Oh, Nutella. You can't just like food; you have to understand it. You have to be able to write quickly, accurately and accurately by the deadline.
You can't let people use you for advertising. You have to be reliable and perhaps charismatic enough to gain followers. Nobody pays you to eat. You get paid to write, and you write well.
