Yes, I’m not entirely certain Impossible meat is equivalent in taste to animal-based ground beef. However, I do find the evidence I cite in the second paragraph of this section somewhat compelling.
Are you referring to the blind taste test? It seems like that’s the only direct evidence on this question.
It doesn’t look like the preparations are necessarily analogous. At a minimum the plant burger had 6x more salt. All burgers were served with a “pinch” of salt but it’s hard to know what that means, and in any case the plant burger probably ended up at least 2x as salty.[1] You note this as a complicating factor, but salt has a huge impact on taste and it seems to me like it can easily dominate the results of a 2-3 bite taste test between vaguely comparable foods.
I also have no idea at all how good or bad the comparison burger was. Food varies a lot. (It’s kind of coincidental the salt happened to show up in the nutrition information—otherwise I wouldn’t even be able to make this concrete criticism). It seems really hard to draw conclusions about taste competitiveness of a meat substitute from this kind of n=1 study, beyond saying that you are in the same vague zone.
Have you compared these foods yourself? I eat both of them regularly. Taste competitiveness seemed plausible the first time I ate impossible ground beef, but at this point the difference feels obviously large. I seriously doubt that the typical omnivore would consider them equivalent after eating them a few times.
Overall, despite these caveats on taste, lots of plant-based meat was still sold, so it was “good enough” in some sense, but there was still potentially little resulting displacement of beef (although maybe somewhat more of chicken).
My conclusion would be: plant substitutes are good enough that some people will eat them, but bad enough that some people won’t. They are better than some foods and worse than others.
It feels like you are simultaneously arguing that high uptake is a sign that taste is “good enough,” and that low uptake is a sign that “good enough” taste isn’t sufficient to replace meat. I don’t think you can have it both ways, it’s not like there is a “good enough” threshold where sales jump up to the same level as if you had competitive taste. Better taste just continuously helps with sales.
I agree and discuss this issue some in the Taste section. In short, this is part of why I think informed taste tests would be more relevant than blind: in naturalistic settings, it is possible that people would report not liking the taste of PBM even though it passes a blind taste test. So I think this accurately reflects what we should expect in practice.
I disagree. Right now I think that plant-based meat substitutes have a reputation as tasting worse than meat largely because they actually taste worse. People also have memories of disliking previous plant-based substitutes they tried. In the past the gap was even larger and there is inertia in both of these.
If you had taste competitive substitutes, then I think their reputation and perception would likely improve over time. That might be wrong, but I don’t see any evidence here against the common-sense story.
The plant burger had about 330mg vs 66mg of salt. If a “pinch” is 200mg then it would end up exactly 2x as salty. But hard to know exactly what a pinch means, and also it matters if you cook salt into the beef or put a pinch on top, and so on.
Yes. The Sogari blind taste test is indeed affected by saltiness; it also includes an informed taste test similarly effected (but again finding Impossible and animal-based meat tied for first). There is a second blind taste test cited immediately thereafter (Chicken and Burger Alternatives, 2018), although salt levels were not reported.

No, I haven’t.

I agree, food is varied and such comparisons are hard—that’s part of why I argue we should do more taste tests! Can you clarify what you mean by an N of 1 study, as usually this refers to a study with a single participants, but Sogari indeed had many participants. If you’re suggesting comparison against multiple burgers, this gets a bit tricky since one has to decide which burger you actually want to be equivalent to, if that’s your goal.
I disagree. Right now I think that plant-based meat substitutes have a reputation as tasting worse than meat largely because they actually taste worse.
Can you clarify what specifically you disagree with here? I don’t think I especially disagree with anything you wrote that follows from here. Instead, I think it’s indeed perception of taste that matters for the impact of PBM and we can likely best measure that perception with informed, rather than blind, taste tests. Overall, as I write, I think actually operationalizing a taste test to identify whether “taste competitiveness” is obtained is non-trivial. The literature so far neglects such operationalizations. What do you have in mind as an ideal experiment to conduct to measure taste competitiveness?
