I tried to open that link, but Firefox says there is a security risk, so I skipped it.
Doesn't the botulism risk only occur if you bake and then store the potato in that foil?
I only ever wrap a potato in foil if I am baking it directly in charcoals or a campfire.
Well, I opened it so if you dont hear from me for awhile, you'll know why
Yes. The risk is cooking the potato in the foil and storing it in the foil. Which I know a lot of people do.
