Thousand Layers Yam Mooncake

Not satisfied with my first batch of spiral pastries, I made another attempt on this project again. This time I chose an adaptation from Moonlit Mid-Autumn Festival by Choong Su Yin. Somehow, it still doesn't look as good as the one in the recipe.....it should be flakier and the layers should be more distinct.  In the recipe, it stated that the all purpose flour for the oil dough be steamed first then sieved.....which I've omitted...wonder cud it be this step that make it flakier???
