I recently picked up this book from the library,
The Particular Sadness of Lemon Cake by Aimee Bender.
In short, it's about a young girl that can suddenly taste the emotions of the person that prepared the food she eats. (And of course, there's a surprise twist towards the end). Overall, it's a really interesting concept. It begins with her mother - she feels complex emotions like deep longing and unhappiness. She has trouble eating most foods because of the negative emotions she senses.
What a huge burden. Probs couldn't eat a freaking Star Crunch (remember those?) without launching into an existential crisis. (Although the more processed the food is, the more she can tolerate it - b/c machines don't have emotions, obvs). I found myself wondering about the people that prepared my food - are they happy? And on the occasional day when I mentally grumble about making my husband's sandwich while he gets ready for work, I wonder if my bad attitude creeps into the mayo? So sorry, husby, if you ever taste a twinge of grumps in your lunch.
