Turkish Taffy. That was gooooood! Pretty damn chewy, though. I haven’t had it since the 60’s, but there may be a bit of it still stuck to one of my molars.
Shake-a-pudding. By Jello. Annoying jingle, sorta gritty if you didn’t shake it enough, but it was 5th grade comfort food for me.
Beeman’s pepsin chewing gum. Did they ever make a rennin flavor?
There is a reasonable facsimile for Turkish Taffy - It’s called French Chew and is available here
I miss Whip-N-Chill which was an instant mousse type dessert
Bar-B-Q. 'nuff sed.
jello one-two-three. Loved the layers–and they tasted different to me (?).
And mock chicken-miss that, too. (it was veal, btw).
BTW - a lot of foods and other products we think have disappeared are for sale on Hometown Favorites. Check there if you’re really craving something “long gone” - they don’t have it all but they do have a lot of it.
Ohmygod you’re my brother!!! I love Beeman’s and Shake-a-pudding.
Tang and Space Food Sticks were also on our shelves when we were kids.
Here’s a website of memory lane food. It almost makes me cry…

Oooh! Fizzies and nik-l-nips!!! Zotz too!
Thanks!
Marathon bars. Old Coke.
Almost mentioned those too, in my OP!
Nice website. I’ll groove on it more later.
Qadgop, you took the two I specifically came in to mention.
I miss Bonomo Turkish Taffy – available in vanilla, chocolate, strawberry, and banana (yechh!). When it’s cold you can smack it against a wall, and it cracks into convenient-sized pieces you can eat (plus a fair amount of crumbly dust that gets stuck to your hand). When it was hot, it would turn into a viscous stick that wouldn’t shatter, and would stick to the foil wrapper so that, try as you might, you had a piece of foil still stuck to it when you chewed on it that eventually gave your fillings a galvanic response. Ouch!
Turkish Taffy may be no more, but I’ve found an adequate substitute in French Chew Taffy:

As for Shake-Me Puddings, I miss them (along with the neat cup and lid), but you can buy powdered just-add-water pudding mix still (My nearby grocery store in Salt Lake City used to sell it in Bulk!) and use a Tupperware or Rubbermaid cup.
Buckwheats.
Grape Tang.
Creamyburgers: Neopolitan ice cream hugged by two soft, chewy oatmeal cookies, and enrobed in chocolate. Enrobed.
I can’t remember the last time I had a Slow Poke sucker. Loved 'em. Which is strange because I usually hate caramel in any form except a caramel apple.
gulf oysters (raw!!!) from living in new orleans during college. The ones you get here in san francisco are half as big and 3 times as expensive
O Happy Day 
Original flavor Doritos. Hell, even better, TACO flavored Doritos. Now all they have is Doritos that smell like dirty feet.
I second the Marathon Bars. Those were great.
if you order the fizzies I would be curious as to what you think of them now. I tried them about 5 years ago and they were terrible. I believe they stopped making them because of a ban on the sugar substitute, and what they used 5 years ago was terrible! A friend of mine and I ordered a bunch–we ended up giving them to the kids who dropped them in the toilet to watch the water fizz. To drink–not so much. Too bad too, I remember them as one of my favorite childhood candies. Loved putting them in my mouth and foaming 
Decent Mexican food. Having lived in Albuquerque and spent a lot of time otherwise in northern New Mexico, I miss that. There’s Mexican food over here, but it’s a pale imitation.
Regal Crown sours, especially grape. I can’t figure out how such an amazing candy could disappear.
The original Fresca (with cyclamates). The only diet soda that was drinkable. No aftertaste.
This is gonna sound really gross, but it tasted divine.
Back when I lived in Cali, Carl’s Jr. used to serve crinkle cut fries that were fried in (I think) animal fat of some sort. At least that’s what I was told at the time. The reformulation kept us kids from wanting to go there just for fry runs.
How much did I love the older style fries? I would gladly pay $10 for a pint glass full of those fries (vertically aligned of course). The thought of that alone, makes my pleasure sensors twitch with anticipation.
