* Traditionally the recipe uses agar agar (kanten in Japanese) which is derived from algae but I prefer the texture of gelatin over agar agar so I’m using it. But if you want to go with the traditional method, just substitute same amount of agar agar for gelatin.
** If the yokan sticks, you can put the mold in a warm water bath for about 30 seconds which will loosen the gelatin hold from the edges of the container
