Kuhn Rikon's ingenious "no-spring" version of the springform pan makes it easy to create perfect quiches, tarts, cheesecakes, layer cakes and more. Traditional spring pans not only leak, they're fussy to use. Kuhn Rikon PushPan features a silicone ring to seal it shut so it never leaks. It's incredibly easy to release - no need to use a knife - just place it on a can or bowl and push down on sides. It evenly cooks and browns you yummy creations.
