I’m feeling chaotic so I’m gonna make a thread of things that look delicious but you can’t eat because you’ll die.
Ahem:

First one’s obvious.
Lava.
It looks like it would be delicious, fruity, and creamy.
But it can melt bone.

Second up is that fluid in glow sticks.
I imagine they’d taste like pixie sticks or smarties.

Thirdly:
Minecraft meat.
I always get super-hungry when I play Minecraft and, having to wait for it in the furnace makes it worse.
Can’t kill you, but also you can’t eat it.
So it hurts you emotionally.

Fourth:
Guy Fieri’s delicious man-ass.
No, I will not explain further.

Fifth:
Concrete
It looks rich, smooth, and chocolate-flavored with a hint of coffee.
Eating it will kill you.

Sixth
The ACNH Switch.
I’m not 100% sure you can’t eat it, but I saw it’s going for 1k on eBay so financially you shouldn’t.

Seventh
Bees.
They just look like yummy little snacks.

Eighth
Ok, I have to ACTIVELY remind myself when I’m painting that IF I EAT THE OIL PAINT, I WILL DIE
I - a full grown adult woman - have to verbally, out-loud, say “Tay, no, you can’t.”
ESPECIALLY
On a palette knife!
Because it looks like spreadable cheese then!
