What is OPOS? OPOS is a scientific cooking technique designed to unchain you from the kitchen, cut drudgery and empower anyone to cook confidently. All OPOS recipes use One Pot & all cooking is done at One Shot. No steps. No supervision. No fear. With OPOS, all recipes from Malai Kofta to Mysorepak are easier and faster than cooking instant noodles! The OPOS Story Traditional recipes do not work for many of us struggling to cope with a fast paced life. We lack the skill, time & support to make them work. Those living abroad face special problems, with even a tadka becoming impossible! OPOS was designed to address these problems. It is being constantly shaped by the feedback of thousands of volunteers from over 20 countries across the world. An OPOS recipe is frozen only after it has been validated by dozens of volunteers, who have grown up with these recipes. Some recipes have clocked over 200 validations. It has taken 13 years, 780 blog posts, 11097 volunteers, hundreds of kgs of provisions, 1208 files, 10411 posts, 5601 photos, 181 videos, thousands of arguments, 4 restaurants, 16 chefs, 14 events & 22 corporate demos before the first set of OPOS recipes were created ! Why OPOS? OPOS is Green. One vessel to wash. OPOS is Clean. Hygienic by design. OPOS is Fast. Fresh food in minutes. OPOS is Liberating. No supervision. OPOS is Healthy. Less oil & salt used. OPOS is Flexible. Cook your way. OPOS is Economical. Saves fuel. ... but OPOS is Addictive! There is no turning back!
