What is your weirdest comfort food or habit? - Leminal Space

The more obscure the better!

Comfort food: Drop dumplings (simple flour, salt, water only) in chicken broth. No veggies. No meat. Just dumplings.

Comfort activity: hiding in a closet. I am nearly 40 and will still do this XD

what is simple flour? also, what is water only?
