From the word “scrimp” to meaning fastidious, to stylish, to a word of praise and, in food, deliciousness.  The adverb “scrumptiously” is attested from the 1800s.  I had rather wished that it was a word unique to Gollum, who uses it in an extraordinary blend of odd, alien, ridiculous, word-playful, and cannibalistically horrifying.
