I would like to make a pot of gold for a St. Patrick's Day cake and thought it would be neat to have the "nuggets" be gold marshmellows, but am stumped as how th color marshmellows? Any ideas?

you could probably paint them with gold luster dust.

How about if you dipped them in gold tinted candy melts? You could dust them with luster dust after they hardened back up if you wanted.

I've airbrushed marshmallows before. You could use the color sprays to do it.

mmmmmmmmmm, marshmallows & candy melts sound like a good combination..
