Funeral Potatoes is a story written by shukyou. It ran in Issue 67 at http://www.shousetsubangbang.com/mirror/funeral-potatoes/.
A death in the family deserves some comfort food.
This is what happens when your research takes over your brain and you have no choice but to use it for evil.
The story takes place in Houston, July 1983. Every non-private-home location mentioned and visited in this story is real, as is the Wednesday night steak night at the Brazos River Bottom. So are funeral potatoes, and you can find recipes all over online. Just pick the one that sounds the most disgustingly decadent and go for it.
