I read it incorrectly as 2/3 instead of 2-3 chef spoons of cream. This means I used "not enough" in my recent micro cook. It means my previous answer to Donald Brasco is out of context. My apology Donald, but I don't think it changes much. As to your question to Phil, I think the 2-3 chef spoons mentioned by Syed is already the amount used for the 1 kg amount, he demonstrated in the video. I would think that in the commercial quantity he uses more.
In relation to my micro version, instead of 1 tsp, the correct amount would be 1 TBSP or a little bit more. Will it make much difference? Probably not and it will be my practice to omit it anyway, for the reasons already mentioned (lactose intolerance and the use of cream only in certain dishes).
The main thing is that this Base Gravy is a good one, even with no cream, and it produces great curry using Syed's recipes and Mixed curry powder. Out of interest I will add some extra cream to the base gravy I have left for my next cook.
