Theme: Across + Down. Clues are provided at the Across numbers but not for the down numbers. Ergo, two-word answers with the same initial letter.
1-Across/Down: Corn or cotton = Cash crop
5-Across/Down: Western wear = Jean jacket
9-Across/Down: Where the Pilgrims first landed in the New World = Cape Cod
15-Across/Down: Homer Simpson’s workplace = Power plant
27-Across/Down: Dessert often made with cream cheese frosting = Carrot cake
40-Across/Down: Places where wheat are stored? = Bread box
44-Across/Down: New U.N. member of 2011 = South Sudan
47-Across/Down: Lab item = Bunsen burner
48-Across/Down: Alternative to a fade-out in a movie ending = Freeze frame
I figured out the theme quite easily. Still, getting all the fills wasn’t entirely a snap with the South Sudan section of the grid giving me the most difficulty. I was able to fill in the rest of the grid on Thursday but didn’t figure out all the answers for that section until Friday morning.
Some interesting answers including a few from the South Sudan section:
25-Across: Feature of Polyphemus from “The Odyssey.” Answer: One eye.
31-Across: Comic Cenac formerly of “The Daily Show.” Answer: Wyatt. (Not a show that I watch.)
41-Across: Org. with an antipiracy stance. Answer: MPAA (Motion Picture Association of America).
26-Down: Word origin. Answer: Etymon.
38-Down: Architect Louis. Answer: Kahn.
