I finally tried the good parchment liners after years of the cheap foil ones. The difference is night and day, my cupcakes came out without sticking and kept their shape for once. The cheap ones always peeled off half the cake and left a greasy mess. My sister in Philly swore by them so I gave in and bought a box for $4.50... anyone else notice this or am I just bad at peeling foil liners?
