I've based the recipe on something which I believe is not dissimilar to that used by Fuller's and brought the gravity down a tad. As I'm short on Fuggles, I'm going to try Williamette as the hop. As the beer style is more about the malts than the hop, this hopefully shouldn't detract from what should be a decent pint.
In fact, it wasn't until after I put the recipe together that I read in Beersmith that Williamette is used in Sierra Nevada Porter. I've not had the opportunity to try the American beer, but it's encouraging that my thought of using Williamette as a substitute wasn't wide of the mark - although whether the American interpretation of a porter is the same as ours, I'm not sure.
