IN BAD TASTE
This might be one of my favorite Sundays in a while, although it certainly played very easy. I finished it in a little over half my typical Sunday time. But the theme made me chuckle, and I thought it was carried out nearly flawlessly.
We get a set of idioms for how things might go badly in various ways. Taking the first word from each, you get a set of directions that might be found in a cooking manual, thus setting up the revealer, ARECIPEFORDISASTER. Very nicely done, with a perfect revealer.
The only issues I had with the list of idioms are these: first, MIXONESMETAPHORS feels so mild as a bad outcome compared to the others. The worst it will get you is a mild look of distaste, and when done intentionally, might even get you a laugh. And to top it, there's that "one's" in the middle of it, which doesn't show up in the other idioms.
My second issue is a total nitpick. SERVESTWOMASTERS is the only answer in that verb form. All the others are in I/you format, while this one is in he/she format. That just makes the final run of directions feel a little off: stir... mix... beat... pour... cut... ...serves?
The rest of the puzzle is reasonably smooth with only an annoying URBANII or a silly CTS here and there. I found most of the clues and answers to be very straightforward, with few misdirections to challenge me. 23A: Vertical part of a plane (YAXIS) took a second, in part because it crossed 3D: Prepare to take off (TAXI), which made me misinterpret the meaning of "plane" in the clue. I also took a moment or two around the crossing of GLAM and GNAR, which gets my least fave answer for today.
1A: "____ Davis Eyes," 1981 #1 hit (BETTE) - B. I am reminded of the Dire Straits lyric: "Don't know how you came to get those Bette Davis knees..."
Fave: OCTAVES (67D: Scales span them). Nicely done.
