Hi Malacara
Pleased that it went okay for you. I think you are the first to comment on the newer "definitive" recipe so far.
I tend to agree with the comment on the salt, as I thought the same. Having said that, I think it's probably better to have too little as opposed to having too much, as salt can always be added later, to taste.
Despite now specifying the amount of water to be added at both stages, the amount actually remaining in the final gravy will depend on the evaporation rate during the cooking process, particularly during the final stage when the pan is uncovered and we're on a vigorous simmer. This will vary from person to person, according to heat settings, and to a lesser extent the material, shape and diameter of the cooking pot.
If however at the end of the cooking process there is not much oil at the surface (particularly after the gravy has rested a few minutes), it may be down to the gravy being slightly too thick. Add some hot water (eg: 250 ml), and cook for another 5 - 10 minutes.
The oil should then separate.

I'd be interested to know if anyone else has tried the newest version yet?
