I have been following RK's recipes from a while. I am still unclear if we can do this without a 2 litre cooker?

Yes you can Sonia. But a 2 litre is mentioned as a starting point just to make sure you familiarise yourself with the technique before venturing out to your own experiments. And this only to make sure someone is able to assist you in case of any mistakes. Otherwise its very hard to guide without knowing where exactly things got haywire. Since I am quite familiar with certain recipes, I have tried it with 3L/ 3.5L myself to satisfy the needs of my family and they have worked out great! :) --DK
