"The meat we could boil -- when we could get a pot -- broil, roast, or fry ... The bread we could bake or fry, the latter mode was generally practiced, for it was the less trouble and the less time of the two modes; the former mode we usually practiced by wrapping the stiff, shortened dough in a spiral manner around our ramrods... where it would bake into a most esculent bread." (p. 78)Gardening manuals and catalogues from the early 19th century were also quoted in the book; these used esculent to distinguish edible growing vegetables from flowers that were decorative rather than edible. I believe that the word is used less frequently now than it was in the 19th century.
Cromulent is a totally new word for our time, quite often used in pop sources. It was invented for a 1996 episode of "The Simpsons" -- as you no doubt know if you are a fan. It's now pretty widely used as a kind of random positive adjective, so it could be defined as meaning "just fine." Or something like that. It's also defined as "Appearing legitimate but actually being spurious." (Dictionary of American Slang).
The Merriam-Webster dictionary, which doesn't actually include it as a "word," discusses cromulent at some length, including this summary of the first instance of the word:
"The schoolchildren of Springfield are watching a film about the founding father of Springfield, Jebediah Springfield. The film ends with Jebediah intoning, 'A noble spirit embiggens the smallest man.' One teacher at the back of the room leans over to another and says that she’d never heard the word embiggen before she moved to Springfield. 'I don't know why,' the other teacher replies. 'It's a perfectly cromulent word.'"The writers of The Simpsons had evidently been challenged to invent two plausible but not-real words, and came up with both "embiggen" and "cromulent." (Though there are a few earlier, more obscure citations for "embiggen.") Both are now rather widely used! Merriam-Webster concludes:
"While we don’t yet enter cromulent into our dictionaries, it’s a perfectly cromulent candidate for future entry."
