The cornstarch replacement for talc is one of the most

volatile powered grains. Can cause explosions. Also under certain conditions it can host bacteria and fungi. I demonstrated to my wife how cornstarch blown into an open flame resembled a blow torch.

and then there is DiHydrogen Monoxide a very deadly chemical compound - https://www.dhmo.org/facts.html. You don't want to know what you get when those two compounds are mixed.

bags of it in farm supply stores here in Georgia, right alongside the ammonium nitrate. Blew my mind first time I saw it!

The exceptions are powders that are carbon free or very low in organic compounds.
All grains consist preponderantly of carbon compounds.
One of the worst powder explosions was at Georgia Sugar. After that powder cloud blast, only about 40% of the plant was standing.
And if you think cornstarch will flare, try cover creamer powder. Shazam!

or juice up a fire. I heard the peanut butter was highly flammable, too. But we never tried to find out.

I know I'm picking a technical not, here.
Peanut oil is combustible, in the same was edible (so to speak) candles are. They're made of animal fats, (or the derived fatty acids) or the equivalent from hydrogenated vegetable oils.
So, definitely peanut butter will burn.
Activation energy is high though, so a stray spark is not going to make it flame.

Wow.

I demonstrated a bazooka to my wife once, but she managed to swerve the car just in the nick of time.

I’ll have to get me some corn starch.

...then I understand.
But, cornstarch is not really any more conflagrating than flour, coffee creamer, espresso ground coffee, etc.
And the danger is really caused by densely dispersing it as a cloud.
It's not to be confused with a true explosive.
Having a gas can for the mower in your garage is a far greater danger.
