These nearly translucent, soft steamed rice crepes are served plain with slices of gio lua (sausage), or they are filled and shaped into small rolls, as they are here. Finished with cilantro, shallots, thit rouc bông (cotton pork), and a little sauce, these rolls were one of my father’s favorite foods to prepare for our family when I was growing up. In Vietnam, making bánh cuon was usually left to professional cooks who had mastered the technique of steaming a thin rice batter on fabric stretched over a pot of boiling water. In the 1970s, Vietnamese expatriates devised an easier method of making the crepes in a nonstick skillet. For the batter, they blended cake flour (very fine, soft Thai rice flour was not readily available then) with tapioca starch and cornstarch. While that approach works fine, I prefer to use Thai rice flour in place of the cake flour because it yields a more delicate result that is closer to the original version. The tapioca starch and cornstarch help the batter set up nicely and contribute to achieving the tender yet chewy texture of the traditional crepes.
These rolls are at their best when freshly made, but they may be prepared in advance and refrigerated in an airtight container for 2 days. Bring to room temperature and then reheat in a microwave oven just until they soften and are warm.
