Anything repeatedly used across recipes is defined as an OPOS Staple. These are building blocks of cuisines which can be made in bulk and stored in our kitchens, to make cooking painless. This book focuses on the ingredients which can be considered as staples in OPOS. Be it spice powders / pastes / dips / dressings / bases, the main idea of a staple is to avoid repetition and enable modular cooking. The idea of using modules exists in every field. In home design, you set up a modular kitchen or bedroom by just invoking pre built units. In software, you have a set of subroutines you can invoke to do often repeated steps. In OPOS, we build complex recipes from ground up, across cuisines, by just using different staples. We can easily jump cuisines, create complex recipes or new fusion cuisines by just adding/ deleting the appropriate staples. This book uncovers the core staples used in a wide variety of cuisine - both Indian and International. It will teach you to create a huge variety almost instantly. The author team comprising of Ashwini B, Srilakshmi Anand, Tazin Faiz and Visalakshi Venkataraman hope to take OPOS to everyone to ensure cooking becomes a non-issue for all.
