George - thank you for the value added. I know I've seen this technique as far south as Manchester.
Rubydoo - the g/g is properly cooked out matey, honestly! The base sauce has enough oil to do it. I know it's hard to go against what we normally do (I used the 'oil in first then g/g, mix, methi etc' method for 20 years so it was hard for me too!) I suppose I was blind to the method as it promised a Glasgow Curry - and I wanted that a lot!
I understand that some won't try it because it doesn't fit their window of acceptability but I'm cooking it and it tastes how I expected. If that, to some, by assumption, means raw g/g and tom paste then they underestimate how well I can cook and how good the results are...but I know it's not gonna be loved by eeveryone, I've tasted some utter garbage in restaurants that have had customers actually in it - although not many, lol!
Regards,
Martin
