I will try it again. It found that it started to happen a little when I didn't stir but then the curry would stick to the pan. I guess I'm just not doing it for long enough, or maybe I'm cooking it too gently. SnS's photo of when it fuses looks exactly how I want mine too, so I guess I'm on the right track. How long would you say it takes to get from adding the first sauce to this stage?
