OH, so now you are agreeing with me, or not so much?

I did say there are no universal edibility tests. I will repeat that.

There is only one exception I would make.
If you eat it and live it is edible, if you die it isn't.
Other than that, nope.
(edit: note that this is not a recommended test for unknown plants)

Even peanuts, which we count as safe, will kill some people.

Maybe we should talk a bit more about personal testing to make sure you don't react to a food if you nave never tried it before?
(Especially since we are on such good terms now)

Edit: Careful not to hurt your hand there guy!
