Here is their page on pasta alla Norma, with both a traditional recipe card and a video. The famous Sicilian dish was apparently named after native son and composer Vincenzo Bellini from Catania, who wrote the opera by the same name.
While they call for spaghetti in the recipe, it is more usually prepared with short pasta. The preparation is fairly straightforward, the only obstacle being procuring the ricotta salata, which can be found in specialty stores. If unavailable, try substituting a good Pecorino or even crumbled feta.
