It was hot as  

I ordered at 10 on 1-10, cuz I'm a chili head, but watching the carbs i went without out rice.  But they had counted on the rice in measuring the heat, so it was much hotter than I expected.  My eyeballs were sweating! 

It might not have been sinew, but that is what it said on the menu.  When I looked at it, I though that it might look like slicing of the casing, rather than the inner fibers, but I don't know.
