This is a true South African heritage recipe! The recipe originally comes from the Dutch settlers of the Cape. It is a staple on the tea table in many South African homes. There is many variations but the almond essence(instead of vanilla) is what sets the South African version apart from the rest. Some South African recipes for "Melk Tert" also includes lemon or naartjie rind. It's so good, Jamie Oliver even has a version of the Milk Tart in his book "Jamie's Comfort Food".
