I've just tried them recently and find they don't have much taste but I put them through a stir fry and they bulk it up nicely. The ones I get you rinse in cold water first, lots of rinsing. Then soak in hot water for 1 minute and throw through the stir fry at the last minute. Don't over cook.
Or maybe I just like boiled rubber bands
