Vietnamese rice paper wrappers (also called báhn tráng) are easy to work with once you’ve moistened one or two and gotten a feel for how they soften up. You can also serve these wraps as appetizers by slicing them in half on the bias and serving them standing pointy-end up.
Spicy sprouts, such as broccoli, arugula, or leek, give sushi rolls a delicate crunch and peppery flavor. A sushi mat makes it easy to wrap the nori and rice tightly around fillings, but it’s not necessary.
Look for caper berries near the olives in the supermarket; they should be next to the capers, but they're much bigger and have a stem. In a pinch, substitute about a tablespoon of chopped capers. Japanese eggplants have thinner skins than typical globe eggplants, so you can leave the peel on. The light purple color is pretty, too.
Note: I prefer using Carnaroli rice for its slightly longer grains and firmer texture. Feel free to use any risotto-style rice like Arborio or Vailone Nano. About the author: J. Kenji Lopez-Alt is the Chief Creative...
