Culturing Buttermilk

My new thing is culturing buttermilk because all I do is place milk and live buttermilk starter from the last batch in a mason jar above the oven (like Oblomov* who sleeps on the shelf above the oven) and it thickens overnight!

Oblomov is a great name for our cat that sleeps in the sun.

*Oblomov (Russian: Обломов; [ɐˈbloməf]) is the second novel by Russian writer Ivan Goncharov, first published in 1859. Oblomov is the central character of the novel, portrayed as the ultimate incarnation of the superfluous man, a symbolic character in 19th-century Russian literature. Oblomov is a young, generous nobleman who seems incapable of making important decisions or undertaking any significant actions. Throughout the novel he rarely leaves his room or bed and just manages to move from his bed to a chair in the first 50 pages. The book was considered a satire of Russian nobility whose social and economic function was increasingly questioned in mid-nineteenth century Russia.
The novel was popular when it came out, and some of its characters and devices have imprinted on Russian culture and language.
