Now Re-Reading: JBC's 秋の牢獄 (Autumn Prison) 🍁 Discussion Thread

I believe it goes, if I open the fridge, the pork and cabbage that should have been used already will still be there, It was the most ominous thing.
冷蔵庫を開けば= If I open the fridge
一度使いきったはずの豚肉とキャベツ= the pork and cabbage that should have once been used
入っており= Is currently inside
不気味なこと= ominous thing
この上なかった= The most
Please correct me if I am wrong.
edit: @NickNickovich In fact I was, おり is from the verb おる which also means to be like いる。 So you can imagine it as the same meaning as 入っている, its currently in the fridge. I got mixed with おく because I was just looking at it which means to do something in preparation. ごめん

@Coldxice Yes, you can find out where to purchase and how in the description of this thread.
