The thing that really gets me is that Jamie Oliver is a chef, with a lot of experience. He's done hundreds, maybe thousands of TV appearances. He knows how to make food, and he knows how to present. He is a brilliant choice for a new cooking show.
This isn't a documentary about being poor, having to survive on pennies a day or anything like that. It's a bloody cookery show to help people during lockdown.
Just because Jack has been poor, and has made a few books about making food from tinned ingredients, it doesn't mean she is a good fit for this new show. As many people have said on here, her presenting style is awkward and makes people feel on edge and uncomfortable. Her recipe ideas do seem to be pretty much "tip these things together and mix".
Although I do believe that experience can be invaluable, the important skill required here is being able to cook and present TV rather than being authentically poor or having a book about tinned produce.
Tinned foods are just ingredients, and to act as though she has more rights to them than Jamie because she used to be poor is odd. The people who have encouraged her should be ashamed of themselves. I am all for helping your pals and giving people a leg up, but you have to be realistic and you certainly shouldn't do it at the expense of others.
