Fair question Steve but I did say something like if/as needed/desired and intended to indicate you could adjust a little at that stage if you wished. I have added both double cream and milk to my own attempts but have not added either salt or pepper.

As a general rule, I tend not to add salt to my own cooking, not even to boil potatoes... and reserve the condiment for chips but I'm sure there are times I feel something does need a touch of it.
