Hi, Just had a host wo states she doesn't know how to use the inserts for a springform pan she purchased in 2000! Seems there's a heart shape and some fluted shape that came with the pan. She lost the use and care card, and I couldn't find it in CC. Does anyone know what this is, and how to use it? I didn't know about PC products until this past Nov, so I'm no help! lol Any info would be appreciated!
