Because they looked good and I had never experimented with them, I bought a package of fresh (not dried) rice noodles. Shrimp noodles to be exact. They come in a package stuck together in one near-solid mass. How do I get them to separate? I tried simply putting the whole mass in a pot of boiling water, but they don't separate. And no matter how gently I prodded them to try to coax them into separating, they just broke apart into bits rather than separating.
