I don't have a 2 liter stainless steel cooker/ induction stove! What Should I do?

Buy them - else you need to figure out the right timings.

My cooker does not whistle!

Get it checked. Most Indian cookers whistle.

How can I scale up the recipes?

Most recipes serve 2 (otherwise mentioned in the recipe). When you scale up, cooking time varies, but whistles remain the same.

How to check my cooker?

Add 1/4C water to your 2L cooker. On high heat, first whistle comes in around 1 minute. On medium heat, it takes around 3 minutes. On details on how to do this (namely Standardising your cooker), please check out this link - What is OPOS? for a video.

Food is overcooked/ undercooked? What happened?

Reduce/ increase cooking time.

Food is burnt!?

Reduce cooking time/ add more water. Use standard equipment. Do not cook beyond 5 minutes for no water recipes.

Food has a raw smell!

Use roasted spices/ OPOS ginger garlic/ onion pastes.

Recipes do not work for me !

Check your cooker. Cook at 600W/ 1200W settings as per the recipe. If using gas/ electric stoves, check timings by heating 1/4C of water in your 2l cooker.


  • Pressure cooking is always with whistle on, right from the beginning.
  • Do not use an inner vessel/ add water, unless the recipe calls for it.
  • Preheat electric stove tops before cooking and remove cooker after cooking.
  • Safety first! Understand a recipe before attempting it !

Hi sir, I read that OPOS recipes needs some ingredients like tamarind paste, gg paste, cooked legumes in advance and are stored in refrigerator. I don't have refrigerator so how do I do it. For instance I can cook legumes on a day to day basis but cannot carmelize onion the OPOS way. Please help Beginner here. Ready to start OPOSing.

Hi sir, Saw yr recipes and very much interested in yr hassle free and easy cooking. How can I buy opos cooker? Thank u Shyamala

Hey Shyamala - are you a regular oposer? For starting out, you can use your regular pressure cooker for these recipes. RK has come out with an OPOS Kit that he is slowly making available to people. When it happens on a larger scale, I will make an announcement in the blog soon. :) --DK

good receipes. When i cook vegetable biryani for 5 people do i increase the ingredients proportionately. What size cooker should i use? Do i follow the same timing and whistles?Itwould be useful if you guide me on this.

I would suggest doing it twice in the beginning. Once you get comfortable, slowly scale up.--DK

Hi can u help me do Mango Virgo OPOS way? I tried today. 1c sugar, 1/2cup water ... left in cooker for 5 whistles. The. I added ghee, 1 cup almond flour, 1 cup mango pulp, 3/4 unsweetened khoa. Turned out like a halwa instead of a burfi. Please suggest changes to get a burfi out of this OPOS way . Thanks

Will def. post a OPOS burfi that you can use as a baseline for your own recipes. As for your question - I apologise, I have no idea what Mango virgo is. --DK
