Frozen mash, is it really unhealthy?

[WeAreOnTheRoadToNowhere]

I ate at a friend's and she used frozen mash. I was very impressed, lovely and no lumps
It is so convenient. According to the packet it only has potato and butter in it but am I kidding myself?
I guess it is considered UPF but how unhealthy is it?

I enjoy watching food production methods, Wilkin Tiptree have some online and Maldon Salt, and lots of different cheese production ones. Inside the factory was good, despite GregG and his poor attempts at humour, I hope they bring that back with another presenter

I often buy the ready mash when it’s yellow sticker and about 20p and freeze it.

honestly 5 minutes in the microwave and it’s no different to spending 30 minutes making your own!
