This recipe is just one of many traditional South African snakcs. It is a very filling snack and I normally either fill them with a curried beef mince or savary mince. Any type of filling may be used and some folks even add jam to it.There are many recipes out there on how to make these vetkoeks, but most do not come out hollow. I have experimented for a long time until I got mine right. The secret is to roll it out with a rolling pin and use a cookie cutter or a tin can opened at both ends.
