Miracle Whip is only good for lubing septic tank pumping hoses.
I work with a person who eats spam, cheese whiz and miracle whip on white bread sandwiches with funyons on the side everyday for lunch. She washes it all down with a nice Fresca. She thought the miracle whip in instant potatoes sounded absolultely gourmet.
Fresca.
Lyndon Baines Johnson drank Fresca.
But I digress.
Miracle whip kick your asses you motherfuckers. How dare you all speak of that great condiment in suach a way. I am truly offended.
Seriously, it sounds pretty good Mr. I may try it. I prefer mw over mayo, but I eat both. I’m simply shocked that most of you hate it. That’s all we have in our house. I say to hell with hellmans…It’s miracle all the way you schmucks… 
Insulting such a wonderfull kosher kondiment in Yiddish?
Oye gevalt! Such an insult already!
My second will call on you in the morning! Brickbats at half a mile.

Miracle Whip in mashed potatoes? Miracle Whip in ANYTHING? Oh, GAG.
Real mayonnaise or nothing.
I’d like to say that I, too, find the concept of Miracle Whip added to anything offensive.
That being said, while I would never buy instant mashed 'taters as an adult, I grew up in a processed-food house, and I used to like to put mustard in the instant spuds, and sometimes I’d get all crazy with it, adding tinned peas and microwaving the whole mess until they were hot.
I feel much better now, thank you.
My theory is that, on a cellular level, we know that instant mashed potatos are fundamentally wrong, and so we are compelled to try to add things to them to mitigate their inherent evil. Unfortunately, if you’re likely to have instant potatoes in the house, chances are that your range of available additives consists of equally vile materials. (I should mention that the “mustard” I referred to earlier is that horrible fluorescent yellow crap which is to real mustard as Miracle Whip is to mayonaisse.)
I have personally never really experienced Miracle Whip - we always had real mayonnaise in my house - and I’ll tell you my household was the minority here in the mid-south. “You don’t have Miracle Whip? What? Everyone has Miracle Whip.”
Now I see that I was missing nothing.
Anyway, back to the OP…I do put ranch dressing in my mashed potatoes, real or instant. Not enough to make them really “ranchy”, just have more flavor. Is that comparable to putting Miracle Whip in potatoes?
