The Centre for Genomic Gastronomy brings us this playful pubic performance around the serious issue of heavy air pollution in Indian cities. By whipping up egg foams in different busy street corners of Bangalore and making them into cookies, one could literally test and taste for different pollutants. As the artists Zack Denfield and Cat Kramer (of CGG) put it “The tragedy of the commons never tasted so good!”. They are also at pains to point out that eating these toxins is no more harmful than breathing them, something city residents do all the time without thinking. Like a Trojan horse these ‘smog cookies’ brought new attention to a mostly invisible issue.
