ANSWER:

No problem in licking it as this is not eating, and Allah knows best. 

I eat food with my right hand, but I was wondering if some food happens to touch the left, is it permissible to lick this off? For instance, if I’m cooking, and some sauce or oil gets on my left hand, can I simply lick this off? Or if I’m eating a sandwich and have to hold it with both hands, and the ketchup spills out and gets on my left fingers, is it permissible to lick it off?

I don’t believe it is permissable to eat from silver unentils (spoon/fork/knife) What does it mean by silver? Anything that looks silver/shiny in colour? Or is it the material it is made from?
