Correct in every way SS. However until such times as Latif's Inspired presents an accurately measured list of ingredients, and same for his tomato puree, this will unfortunately not be possible. This may not ever occur. My past experience has shown me that "minor" adjustments, modifications and assumptions are an essential part of my cooking (geographically forced in some instances). I will be making this base (best guess) and I expect that it will be quite acceptable and possibly even good. CT has expressed that it really isn't too different to other bases / gravies and in particular, his own.
