Sometime around 2010, the first photo of a tofu cake (or was it a mango salad?) appeared on my Facebook feed. What was my reaction? I wish I remembered. Perhaps I smiled. Maybe I “liked” it. Or possibly I turned off my desktop PC (oh, the technology we used in ye olden days!) and headed to the kitchen. Most likely, I ignored it, not realizing that I was just witnessing the birth of a trend soon to sweep the world.
