Maybe I only tried Impossible after they perfected their formula, but in all the meals I’ve cooked with it, like burgers, chili, stuffed peppers, beef stroganoff, meatballs, etc, I wouldn’t be able to tell that it’s not real beef in either flavor or texture unless someone told me.

I cannot say the same for some other alternatives like soy curls, tvp, beyond meat, all of which have a certain ‘off’ flavor. Beyond meat as an example uses pea protein, which seems more difficult to mask.

The only other alternative that I’ve found that can convincingly be beef is Quorn, which if cooked with a bullion cube or marmite can very effectively replace ground beef in most recipes.

Oh, and those mushroom based Meati steaks are also really good and beefy. The texture is softer than real steak, but it works great for steak tacos.
