Hi,
Here is a youtube link (first of a series) which is similar to how we do it in the restaurant, we take it quite a bit darker though before the ginger/garlic stage so that onion is almost a paste taking a good 2 hours or so, and the lid is kept on whilst cooking the onions which could have been done in this prep as well as we don't see the initial part of the cooking.
Curry sauce base 1
You can tell when it is time for the ginger and garlic to be added as the onions are dark, very very dark, not burnt at all though, and the oil has separated. It's usually given a stir every 15mins or so especially at the later stage to prevent sticking on the bottom of the pan.
Hope this helps some, the process even the use of the tomato paste is the same. One major difference though is that we don't blend the gravy due to using whole spices with the cooking onions, and we add some water when tomato paste is added in. Not a lot of water though, it is still a thick concentrated gravy ready for use in various dishes.
Cheers,
Mark
