Yours flavourfully lets users literally taste their emotions by transforming their written letters first into Rasa through machine learning. The word Rasa exhibits a duality - translated simultaneously into emotions in Indian aesthetics and flavours/taste otherwise, then into flavours of Pani Puri, popular street food in India. This emotion, rasa, flavour mapping was done through extensive user research. Users enter their letters on the web app to see their uniquely created Rasa Art and then taste their unique Pani Puri through the physical installation.​

​

The theory of Rasa, in Indian aesthetics, is a highly evolved, ancient conception of base human expressions. They have been used primarily in dance for at least a thousand years. Pani puri is an extremely popular Indian street food which consists of Pani (Flavoured water), filling, and a crunchy puri as the base. 

Combining these two disparate forms hinged on the re-mediation of the letter-form into a taste-form.

For this, we needed to achieve two transformations; One, we needed to transform the letter-form into an emotion-form. We solved this using a custom built recurrent neural network NLP model which detects emotions within a series of sentences and transforms them into a rasa classification.​

Two, we then needed to translate the emotion (Rasa) into a flavour. We utilised the duality of meanings of the word “Rasa” in Sanskrit and other Indian languages - the word “Rasa” is used to denote expressions, taste, and in a more literal form, juice at the same time. Thus, we have readymade access to a tried and tested, culturally relevant classification of emotions which easily bridges the emotion-to-taste gap.
