Made entirely from plants - simple, all-natural ingredients such as wheat, coconut oil, and potatoes. What makes the Impossible Burger unlike all others is an ingredient called heme. Heme is a basic building block of life on Earth, including plants, but its uniquely abundant in meat. We discovered that heme is what makes meat smell, sizzle, bleed, and taste gloriously meaty. Consider it the magic ingredient that makes our burger a carnivores dream. Because we use 0% cows, the Impossible Burger uses a fraction of the Earths natural resources. Compared to cows, the Impossible Burger uses 95% less land, 74% less water, and creates 87% less greenhouse gas emissions.
