“I have good news for mock meat makers who want to challenge the Impossible Burger: You’ll soon have access to Impossible’s magic ingredient — that’s heme, the molecule that makes its plant-based burgers bleed, sizzle, and taste so similar to the real thing.

Last month, Leonard Lerer, CEO of Back of the Yards Algae Sciences (BYAS), a Chicago-based start-up, invited me to a taste test of a beta-version of his heme, which is derived from spirulina, a blue green algae.”
