I recently made a batch of jello shots using 1 oz little paper cups and a lot of the jello mixture leaked right through the cups b/c they were more permeable than I thought. A little more than half remained and solidified in the cups.
I still have about 100 of these little paper cups left and I want to use them for another batch of jello shots.
Does anyone have a solution for sealing the cups so that they don't leak again? (I don't want to use plastic cups b/c they'll just sit in a landfill...)
Maybe a coat of PAM on the outside?
