What material is used to roll a cake tightly?
The towel prevents the cake from sticking to itself when rolled and the powdered sugar prevents the cake from sticking to the towel. Nothing will ruin your attempt at a roll cake like a sticking cake. Immediately peel waxed paper or parchment paper (if used) from the cake and discard.
What makes a cake elastic?
The reason why a cake gets rubbery is that the overmixing of flour activates the gluten. Apart from the Gluten, insufficient creaming of sugar and eggs will also make a tight texture because there isnt enough air trapped in the mix to give it a lift.
