Someone told me that flour (the colder the better) could save you from getting blister should you burn you skin from hot water or direct flame. Put the cold flour all over the injured area for a few minutes to let it stop your skin from developing a blister. How true is this, I haven’t tried it myself. Hopefully I don’t need to try it. So, keep a pack of flour in your fridge just in case that very situation for you to prove whether what I said here is true or not, happens.
