Potion, common
An attempted alchemts fire gone wrong? This alchemist fire had self raising flour as the binding agent creating a self cooking bread.
range 20/60
Damage 1 d4+ strength fire damage, and the target is covered in dough taking 1d4 fire damage every round unless they make a DC 14 dex check to remove the sticky dough.
On hit or miss roll a d6 after that many turns the chemical reaction is complete leaving you with questionable bread, and doing no more damage
