I approve of using saffron and like the taste; however being a vegetarian I would substitute vegetable stock which since I steam a great deal of veggies is no problem, and sodium is no problem either (who on earth would add salt to steaming water?) Plus I think dry sherry may well be tasty but (a) is not that easy to find having fallen out of fashion, sadly, and (b) adds unnecessary calories; true, not that many calories, but what with the exceptionally delicate flavour and extreme expense of the saffron why add sherry too?
