Considering even industry certifications aren’t always followed, I’d have to imagine ones without are even less likely to be followed. Even if they are, they’re almost certainly still doing stuff like Chick culling :(

There’s also some store bought vegan mayo too that’s pretty good! (Though making your own is probably cheaper if you enjoy doing that)

If you like trying things out, I should also note there’s a good number of vegan recipe communities here on Lemmy. For instance:

!homecooks@vegantheoryclub.org

!veganrecipes@sh.itjust.works
