How to Standardise your Pressure cooker?:

Before you start OPOS method of cooking, make sure your pressure cooker is standardised. That is, it works the way it is supposed to in order for the timings in the recipes to work.

Have a doubt whether opos s healthier as we are cooking food in high flame and faster

We are pretty much cooking vegetables to death with long cooking - since all the nutrients are diminished/cooked away. Minimal cooking ensures most of the nutrients are intact but unwanted bacteria is eliminated. You might have read about flash cooking that is considered a healthier and delicious way to cook veggies (color retention and just cooked) where lots of water is boiled, veggies immersed for few minutes and then placed in a cold bath to stop cooking. OPOS cooking is on the same lines. --DK

Tried out an OPOS..ERISSERY today. Pretty good if I must say so. However my onion paste was not Browning.. so I added a few more whistles . Got a good deep brown .. and a thick crust on the bottom of my pan. Had a tough time scrubbing..

If you want a more browned or caramelized onion flavor, use caramelized onions in the recipe instead of just regular onions. OPOS caramelized onions are very simple. --DK

I am a person who had always hated cooking. And being a woman.. I suppose I was stuck with cooking. However you're system is an eye opener.. I Just need to remember the no. Of whistles.. spoons of water and oil.. and hey Presto ..food is ready. However I find the burnt bases ate a tad difficult to clean.. some of the flavours need adapting to.. otherwise.. very good overall

If burnt bases are your fear (and your cooking timing is more or less the same), try adding a bit of water in the bottom starting out. Once you start getting better, slowly reduce it little by little until there is no excess water left in the dish but there is no burnt bottom either :) --DK

i got a new PC but unable to standardize . I am from USA and i do have a gas stove but the whistle wont come within 2 mins. what is the solution . I tried in small medium n big burners

I would suggest few things at this point. 1) Have you tried increasing the flame? 2) If that is not the issue, have you checked if the steam is escaping by the sides? 3) If cooker is not giving out steam, and is otherwise in good working condition, the only thing remaining would be to invest in an induction cooker. Its available in amazon. The reason why this insistence is that we all can have about the same cooking time and is easy to troubleshoot in case anything goes wrong. If even buying an induction is not feasible for you at this point, then it would be a trial based experiments on your own. I would suggest starting safe recipes that involve water and staying around the pc to check if it works.Try the pav bhaji recipe, give it additional 1-2 minutes (from the time listed)/or if you get burning smell to test out the recipe. You will soon understand your pc/stove and will be able to wing it. But like I said earlier, it can prove to be hard to troubleshoot if you do not know when your whistles are coming. Hope this helps Kalpana --DK

I am following traditional cooking. I was surprised when heard about opos technic.How to get clarifications for any doubts and problems during the time of trial.Thank you sir.R.Govindarajan.

Please try recipes exactly as given and tell me any issue faced with details. Will try to rectify them :) --DK

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
