I don't get the mayonnaise hate. I know us white people put it on everything, but it's literally eggs, vinegar, oil, sometimes mustard... I love all of those!
People grow up on the shit tasting commercial crap or (shudders) Miracle Whip and then think all mayo tastes like it
I myself as a younger child fell into this and didn't really like Mayo until my preteen years when I realized that there's actually good tasting mayo out there
I was raised with Miracle Whip and then discovered real mayonnaise as an adult. I introduced my parents to it and they love it now, but they have put the Miracle Whip into the memory hole and insist that we always had real mayonnaise. They also insist we never had liver when "liver night" was a weekly thing for my entire childhood. Miracle Whip is terrible but at least it's not liver.
I like to make my own because it's quick, easy, and much tastier than most store bought, but I also understand that not everyone has an immersion blender or the desire for one.
I like to add fresh herbs to mine. A little dill or parsley really livens it up. I've tried mixing them in store bought and it's not the same.
