Parisian sweets? / FRI 6-10-22 / Blogroll assortment / Root vegetable with stringy stalks / Scientist for whom a part of the brain is named / Common condiment with fajitas

Ironically, the hardest part of the grid for me was, in fact, TEETH. Not because I couldn't understand TEETH, but because I couldn't understand the apparent plural in 2D: Parisian sweets? (CHERIE), which I had rendered as CHERIS, reasoning that if "my sweet" is one person, well then "sweets" is more than one. My dear ones, mes CHERIS, makes sense, moving on ... unfortunately, what I was moving on to was TSETH. And yes, that is a nonsense "word," but the whole "metaphorically" part had me thinking maybe it was some modern slang I didn't know, or something like that (is it a one-syllable exclamation, like "TSETH!," or ... rapper named Seth trying to style himself after T-Pain? I was prepared to believe many things). I had SHORE and actually wanted TEETH at some point, but pulled both out when CHERIS made that whole section seemingly impossible. I also forgot the last letters of the [Root vegetable with stringy stalks]. CELERITY? No. CELERIUM? No. CELERI...AN? No, you're thinking of Valerian. I literally just now *already* forgot CELERIAC, so improbable do its last letter seem to me (seriously, I tried to recall the correct answer without reconsulting the grid sitting on the desk just to my left: failure). CELERIAC sounds like something rabid celery fans might call themselves. After these NW troubles, the puzzle just sort of chugged along at a somewhat slower than usual rate, though the SW went down like a Tuesday and the SE like a Monday, so I guess I can add "very uneven in terms of difficulty" to the list of less-than-ideal features. I had BARGING INTO before INON (and I wanted BURSTING -something earlier in the solve, when I thought it was CELERIUM). COUNTERACTS also gave me some trouble since I didn't have the first letter (that CELERIAC really did a lot of damage). No other errors of note. 

[please replace "Valerie" w/ "Celery," thank you]

Bullets:

• 10D: Some customer service agents nowadays (CHATBOTS) — this is one of the two answers that feel most fresh and modern in this puzzle, but since CHATBOTS are such a dreary and depressing and dehumanizing part of life, I can't say I'm too thrilled to run into them here.
• 15A: "Sounds good, but ... huh-uh" ("YEAH, NO") — this is the fill winner today, by a country mile. A perfect, common, apparently self-contradictory colloquialism. I say some version of it all the time. I love when the puzzle captures weird quirks of speech like this.
• 29A: Like Gen-Z fans of classic rock, seemingly (BORN TOO LATE) — this whole concept doesn't really have the resonance it might have at some pre-internet, pre-streaming, pre-universal music access point. If you're 20 and want to listen to classic rock, it's easily accessible. It's everywhere. OK, your friends aren't into it, maybe, but so much of being young is in fact veering away from the crowd, or trying to. Anyway, BORN TOO LATE implies you're missing out on something, and while you might wish you had been alive to be part of some scene (to have experienced Woodstock, or, I dunno, peak mall culture), the music itself is ubiquitous. You live in an age where you don't even have to *try* to find out about it and listen to it. There it is. In abundance. 
• 22A: Blogroll assortment (SITES)— the very word "blogroll" feels like it's covered in cobwebs, or, like, moldering in a weedy and overgrown field somewhere. Blog culture peaked somewhere in the late '00s, and I honestly haven't thought of this term since ... well, maybe since they got rid of Google Reader. Usually, if you have a list of SITES in your sidebar, you've given them some more meaningful thematic label.
• 1A: Puzzling start? (ACROSS)— I don't get it. Yes, I "start"ed with this clue, which is an ACROSS clue, but I don't get how ACROSS is a "start," necessarily. At all. I thought this answer was going to be a prefix at first. But no. This is an awfully forced "?" clue. I don't even know what kind of wordplay they were going for. I often "start" with the Downs, if the first ACROSSes are all really long. Sigh. "?" clues should make sense! [Puzzling start?] is a good clue for PEE and that's about it.
