well as a kran i have to say some recipes sound delicious some revolting (i hate rats whether live or dead or in my stomach) i do believe that there should be soe sort of hunger system like have you seen someone who can go for 50 years or so without food

on the recipy side i have a terific recipe for krans:
Hard Boiled Steel Paste
Ingredients:
Steel lumps acording to apetite
Utensils:
A very strong hamer maybe
diamond coated
A heat resistant pot i sugest
one made of platinum
Take the steel lumps and smash
them down to mushy goo this
usualy takes 5-7 hours to non
kran so they wont be making this
then place in the pot and leave for a
a few hours also i found thet this recipe
is usefull on hunting trips you can track
a beast while making diner or take a
good nights rest
Bon Apetite Warning this recipe is not sugested for non kran organisms
and besides what other race can take a bite out of pure steel.
