This is a recipe for marshmallows that i came across.... http://homecooking.about.com/od/dessertrecipes/r/bldes164.htm This has two components which i just do not understand. How do i use powdered gelatin in place of sheet gelatin ??? I heard some people say 1lb gelatin powder equals ten sheets... Is this true ? And also, how do i convert the wieght of gelatin into no. of tsp to use ?? Why do we use corn syrup in the above recipe of the marshmallows ???? Any help will be greatly appreciated . Thanks.
