Hi Wayne,
It is a good point that you raise. I would also add to this, you may remember my remarks with regards to the amount of veg/onions that I'd witnessed in my local TA's stock pot, and that of c2g and Dipuraja? The onions clearly over filling the pot. With regards to the c2g base, doesn't he say to add the same amount of water as you have gravy?
So, if I have this correct, his pot looked like a 5L pressure cooker style pot. His veggies/onions came above the brim of the pot and he added about 750ml of liquid (water & oil). Once cooked, it appeared to have around 4L of gravy ingredients before the water was added. Blend, then add equal amounts of water, so, the there would have been around 6-7L of gravy before the 'seasoning' was added.
So with that observed, that rule could apply to any size pot that you use, as long as you stick with the c2g method. Where this methodology falls down, is the amount of spices that you would add to achieve what c2g intends us to? Plus, with the added ambiguity of the exact measurement of a chefspoon, it's always going to give varied results.
I've got to admit, I've never tried to do a gravy with so many solid ingredients and very little liquid as c2g or Dipuraja. It's quite amazing to see actually how much liquid is in the pot once the onions have cooked before blending, especially as he makes no mention to using a lid, which of course would slow down any liquid evaporation.
