I haven't bought it in a while, but is the Hel mann's olive oil mayo--nvm, I looked it up and they actually have a dedicated vegan mayo line, so that's cool.
I'm gonna have to try vegan mayo sometime. Super curious how it compares. Hopefully, it doesn't try to replicate Miracle Whip. Vegan butter, too. It sounds weird and looks very different, but people I trust to have good taste on YouTube have recommended a particular brand of vegan butter over regular dairy butter so I have to assume it's really good.
always happy to read about someone who wants to try vegan food :)
vegan butter is great - it tastes a little off from dairy butter if you're eating it on its own (also depends on brand, some are way better than others) but it is indistinguishable (to me) in a complete dish or baked good.
all the vegan mayo i've had is a great substitute for cheap storebought mayo, but maybe i've just been getting shitty mayo lol. if you're someone who is into the fancier mayos and/or have made your own at home and know how good that can be, i haven't had any vegan stuff that measures up without additional flavorings. but like another commenter said, you can just mix and match flavors until you get something delicious.
Soy milk, neutral flavor oil, and vinegar in a blender makes a really simple vegan mayo. You can play with the flavors until you have something you like.
