Hi Susie in Texas and Fay.
Thank you both very much for your replies.
I have a pressure cooker which I have never used. I find the whole concept of huge amounts of pressure rather intimidating, and have memories of my mother's split pea soup all over the ceiling

I now feel inspired to get it out, read the instruction manual, conquer my fear and give it a go. Especially as I now understand what a 'whistle' means in relation to the cooking time, as opposed to a jiggle, which I think more relates to the temperature - ie the more jiggles per minute means more heat means more pressure. I may be wrong but I suspect that Indian pressure cookers work on a different basis from Australian (/American ?English?) ones, as I have only seen the reference to whistles in Indian recipes. The article All About Pressure Cookers is very useful too, Fay
Wish me luck!
