On the tv programme Delhi Belly, they showed an Indian chef cooking in his restaurant. It was a popular restaurant. He prepared bases. I think there were 3 in total. One was onion. Not sure of the other two.....I was switching back and forward to watch a rugby match at the time. Not sure if the others were tomato and spinach. Did anybody else watch it? Anway, he did say that he cooked the bases for hours on low heat. I mentioned this before in the thread discussing the programme. Anyway, my point is that they do use bases in India too if this guy's restaurant was anything to go by......
