Mmm, latkes. I've never been able to make good ones.
I'll have to have a look for the potato sweets. I've an idea I've heard of them, but I'll have to see if the technique and other ingredients are plausible for the Shire.
Those cookies sound interesting indeed! For authenticity, I think I will make my own plain potato chips (this is what a dehydrator is for!), since Sam should be able to do that in a slow oven. Although authenticity is still a bit tenuous, because potato chips would have to be common for people to start turning them into other things.
Thank you! These are going in the list! Good thing it's autumn here, because I may not have enough potatoes stored in the cellar.
