There should be Potato Kugel (made with schmaltz, of course) and Noodle Kugel. These don't seem to exist in Subeta.
These dishes are tasty and often part of a feast or potluck, so IMO they'd make good Fireside foods.
Kugels? For Fireside? It's too bad nobody had come up with this idea before, not even me! But I really like the idea. The problem is whether to include it in NPC shops or as a recipe for Fantine's Bakery.
We'd need more noodles before they could go into the Bakery! I'm also not sure they would fit in there, as a lot of the stuff at Fantine's rn is more dessert-type foods rather than casseroles/main courses. In terms of NPC shops, I could see it fitting in at Quick Bites as an item that cycles in for the holiday, and then retires for the rest of the year.
they/them/theirs, please.
I'm pretty sure there aren't many noodles in Subeta to use for baking with Fantine. We've been told that not all of Fantine's recipes are meant to be desserts even though most of them seem to be.
There may not be much in the way of potatoes or buckwheat either.
I was thinking that you'd get them from turning in pumpkins to Fantine, or by encountering them at the Bonfire from the Red Rreign who knows good food when she sees it.
