Bellamy Young landed this episode by chance while touring Europe. While she was enjoying a stopover at friend Scott Foley's house in Prague, the producers offered her the part. Foley and Young had co-starred in the popular series Scandal (2012).
Trdelnik is a spit cake, is a European cake made with layers of dough or batter deposited, one at a time, onto a tapered cylindrical rotating spit. The dough is baked by an open fire or a special oven, rotisserie-style. The cooking process is similar for all the spit cakes: they all consist of a dough applied on a spit which is slowly rotated over an open fire or other heat source. One way of doing this is when the spit is dipped several times in a bowl with liquid dough or the thin dough is poured on spit. Depending on the dough's consistency and the spit's speed, it will form a layer on the spit, and when very runny, it will drop, thus producing small spikes, giving the cake a coral-like appearance. The resulting cake consists of many layers of cooked dough, and when cut is shown to consist of rings - hence another name, "tree cake". Alternatively, the dough is wrapped around the spit as spiral threads. In some varieties of the cake, while they maintain the shape of the spit cake, the rings are actually baked separately and attached to each other with icing. Some spit cakes have a smooth surface. Others, like spettekaka and sakotis, have an irregular shape.
