My problem with the Impossible Whopper, at least when I tried it, was that the texture was too much like the bread, so the mouth-feel was off. But maybe I'm so use to eating beef burgers that I expect there to be be gristle/other weird bits to give some texture. I thoroughly enjoy the Beyond Meat burgers, though, as their texture is more meat-like than my admittedly-limited exposure to the Impossible burger.
So an excellent ground beef substitute for “utility” use. Nobody’s buying a fast food hamburger to savor the delicious, high-quality beef or as part of a carefully-planned fitness and nutrition strategy.
Can’t wait to see how the pork variant works out.
