Eidsvold's white chocolate and cranberry fudge what size tin?

[wastwinsetandpearls]

I want to make this recipe but am unsure of what size tin to use.

She says a slice tray but I do not know what that means.

How thick am I aiming for?

however thick you want to make it. I have made it in a swuare tine - and a slice - rectangular tin

roughly 27cm x 15 cm x 3 1/2 cm deep - slice tray
