Addendum

Maybe they have such integrity that they refuse to find terrestrial substitutes for ingredients which will be discovered only in the distant future.

The Missing Element in Science Fiction

There must be one somewhere, but I've never read any science fiction that Redwall's it up with lengthy feast descriptions. Don't these authors want to sell cookbooks?

Animal Comparisons

When you think about it, humans are mice to giants' rats. But then what are hobbits? More littler mice? Meeces? We have to figure out who the good guys are by Redwall rules.

Another Redwall Question

Did the humans all go to the moon? They did, right? It doesn't really seem post-apocalyptic.

Redwall Question

Why do rats gotta be the bad guys, huh? Just look at this picture of one. It looks so . . . ergh. Ugh. Never mind.

Notes on Cuisine

Porridge? More like snorridge!
Fillet? More like get away!
Stew? More like boo!
Ham? More like scam!
Onion? That sounds all right. Just have everybody eat an onion. Big feast scenes are so Redwall.

Non-Multi-Million Idea

Wheel of Thyme, a channel/stream dedicated to reproducing Wheel of Time recipes. That series didn't exactly have a Redwall-like focus on food, but its name is so much more flexible.
