This is the flaky kind of scallion pancake, built on a smear of scallion-lard paste. The paste is made by pouring hot lard over flour and fine-chopped scallions, and it goes on in clumps that melt into the layers as the pancake fries. A yeast dough keeps the crumb tender, and a second proof in the oven makes the discs puff before they see the pan.
