How to Keep Prepared Spring Rolls Fresh
Spring rolls are great party food, and can be prepared ahead, says Anne Le, co-owner of Tamarine restaurant in Palo Alto, California (and former co-owner of Bong Su in San Francisco). She advises that a moist towel can prevent spring roll rigor mortis. Le also offers counsel on softening the rice paper, assembling the rolls, and what to dip them in.
Spring rolls don't last. The moist towel may help a little (as can sealing a package with saran wrap), but these are best eaten within a few minutes of making. Otherwise, it's a big, grainy mush. Shrimp included.
