Flaky Yam Paste Mooncake

My first attempt on such mooncake but was quite disappointed with the final result, suppose to deep fried the pastry in the final stage but the skin turn out very ugly, so bake the rest of after trying deep frying 4 pieces. The spiral was not as uniform as expected, think maybe due to trying to wrap too much filling with the amount of pastry. Recipe adapt from Agnes Chang's mooncake vcd...
