Least appealing answer in the grid, to me, was SEA EEL (44D: Sushi offering). Is there any other legit crossword entry that has the appalling letter string "EAEE" in it?
Theme answers:
18A: Barbecue comfortably? (GRILL AT EASE)
20A: "Are your Southern breakfast vittles satisfactory?" ("GRITS OKAY?")
32A: Marvelous golf club? (GRAND IRON)
35A: Purple outfit? (GRAPE SUIT)
37A: Rules regarding tile setting? (GROUT LAWS)
54A: Big black bird? (GREAT CROW)
56A: Passenger gorging on fried chicken and potato chips? (GREASY RIDER) — winner!
Only a few things were truly out of my comfort zone on this one. Would never have gotten ROSSES without crosses (but did know ROSARIO, which helped). Haven't had chemistry since 1986, so needed many crosses to pick up TITRATE (41D: Measure the strength of, in a way). GRANGER is slightly, vaguely familiar as clued, but I definitely needed crosses, and would have clued it via one of the many GRANGERs you see pictured on the blog today (except Wayne Granger, whom I've actually never heard of).
Bullets:
8A: N'awlins sandwiches (PO' BOYS) — Mmm. "N'awlins" is a good way to clue the equally contracted "PO'"
23A: When doubled, a #3 hit of 1968 or a #1 hit of 1987 ("MONY") — #1! Wow, I had no idea that Billy Idol song was so big. "White Wedding" big!
24A: Nonmigratory goose (NENE) — they pretty much just stay there in Hawaii.
44A: "Little" title figure in a Beach Boys hit (ST. NICK) — wanted DEUCE COUPE so bad.
51A: Silents star Nita (NALDI) — Like DINA, crosswordese, but most solvers seem to have picked this up eventually even if it was initially unfamiliar to them.
That's it. More tomorrow. Oh, if you want to read about a scoring controversy at the Crosswords L.A. tournament — one that resulted in my fellow judge Tyler Hinman's having to be physically restrained and sedated — read his write-up of said controversy here.
A long time ago, I was solving this puzzle and got stuck at an unguessable (to me) crossing: N. C. WYETH crossing NATICK at the "N"—I knew WYETH but forgot his initials, and NATICK ... is a suburb of Boston that I had no hope of knowing. It was clued as someplace the Boston Marathon runs through (???). Anyway, NATICK— the more obscure name in that crossing—became shorthand for an unguessable cross, esp. where the cross involves two proper nouns, neither of which is exceedingly well known. NATICK took hold as crossword slang, and the term can now be both noun ("I had a NATICK in the SW corner...") or verb ("I got NATICKED by 50A / 34D!")
