Touhou Project doujinshi, 「パチュリーのズボラ飯 14」 ("Patchouli's haphazard meals 14", let's say.)  Released by Circle 168 (iroha,) drawn by 15 (touko,) originally released at Winter Comiket in Heisei 28 (2016.)

This doujinshi has a simple premise -- Patchouli eats/cooks delicious food, in this case oden and flan, while talking about it a lot.  It's fun, the same way Yuru Camp is fun.  There's some byplay with Remillia that I don't quite get.  It's also a little weird seeing them use a microwave -- not something one imagines existing in Gensoukyou.

24 pages, including notes and chapter break.  Standard doujinshi B5 size.  Black&white pages, color cover, as pictured.  Entirely in Japanese, as you might guess.  Book is in good condition, no damage or marks on pages.
