... a very scratched sore throat. Some nice cold jelly would be good

In rare instances when I use "Jello" I usually just add hot water to the powder and drink it warm (without letting it "set") as a somewhat soothing treatment for mild upsets of the innards. The Jello is liquid, or at worst "semi-solid," at internal body temperatures, so it doesn't "set up" inside you; and it seems to produce a soothing effect on irritated upper gastric areas.

To clarify for those where markets vary, in the US "Jello®" is a trade name. Their most common product is probably the flavored gelatin powder that maxes with hot water and then sets up into "jelly" (a soft "rubber") when cooled. The "standard" variety contains more sugar than gelatin, but they also offer "sugar free" (artificial sweetener) varieties, with both kinds available in about a dozen flavors.

Jello® also markets "puddings," similarly packaged, that usually are prepared with milk (or some other "milkish stuff"). Both "instant" and versions that require "cooking" are offered in the "puddings."

Unflavored gelatin is also commonly available as a powdered or granular product, but so far as I've seen this is not produced by Jello®. The most commonly seen brand in areas where I took note is Knox®. The Knox people may offer the unflavored gelatin in "cake" form, but I haven't seen that kind for several decades in local markets we've patronized.

The unflavored gelatin is used by some to make the same sort of noxious (is it then Knoxious?) kinds of stuff as with Jello, to cater to special dietary preferences, but may be more often used to simulate "jellied meatish stuff." I can't comment much about such uses, as I've been averse to commiting such atrocities against things otherwise resembling food.

There has been some debate about whether "KoolAid®" is just "Jello without the gelatin," but I doubt whether anyone really knows.
