I've seen the same brand in one of our special english shops here in Stockholm. I bought already made fondant in pastry colours. It tasted.... realy bad and I've been thinking of making marshmallow fondant from scratch instead and see if it tastes any better.
marshmallow fondant does taste way better but for convenience I usually just stick to regular premade fondant. Mine usuall only comes in white and I mix my own colors. From experience, most people usually cut off the fondant covering before eating anyway.
Over here in Sweden we use marzipan on our cakes and many people seem to like it. I myself can't eat it since I am alergic to almonds. It's very sweet and easy to work with but I wuld prefere marshmallow fondant over marzipan.
