Trial Stew

A Trial Stew is an item in Paper Mario: The Thousand Year Door by mixing Couple's Cake with a Poison Shroom. Lowers the user to one HP and down to zero FP.

If it lowered you to just one HP you could make a Mega Rush strategy out of it, but then zero FP? You would need Double Dip to revive FP to make use, then Triple Dip to hide yourself with a Boo Sheet yet! Make the item to complete your cooking inventory, then sell and never use it.
