You mean butter and gravy on mashed isn’t the norm in places? Butter gravy bacon bits cheese sour cream all good just depends on what you are eating with it.
My mom would get all weird. For her it was butter, or gravy on mashed. Not both. Must have been how she was raised. The funny thing is, on a baked tater she'd go butter, chives, bacon bits, grated cheese, pepper, and sour cream. I do that too, but I asked her why she was so weird about mashed when it was all in the table for baked. She never had a good reason for that. Eh, we all have our hangups. I still remember Mom bringing margarine to her sisters house for a Christmas dinner. All of moms sisters and brothers were dairy farmers. Oh boy. The looks that she was given. There were only a couple of words spoken about that blasphemy. Needless to say mom heard about that for decades.
Any type of food on the plate is game for butter and or gravy, preferably both. Same with sour cream on potato/mexican. Goes for bagels and english muffins too, butter and cream cheese. Sometimes mini bagels are just a vehicle to deliver cream cheese.
My wife grew up having to pick potatoes, her uncle owned a huge farm, she hates potatoes to this day. Will only eat mashed reds, sometimes a baked. But to this day she can not pass a Houlton Farms Dairy store. She is not a butter eater and (comes from her father) that’s the only real butter left that other stuff isn’t real butter and margarine is just hardened up pan drippings colored yellow. The ice cream is actually really good there but I can’t do milk so I eat very little of that stuff, just cheese and butter for me.
Ahh yes, margarine, AKA Iowa butter. I remember the pound packs of it where we had to break a color pack in it and work it in good so it would look yellow.
Made the wife breakfast and she wanted French toast. This went on a layer of yooper cream. Not sure why it came out three times.
They should watch the movie "Hidden Figures" and then try to tell their students the correct answers don't matter.
