No, but only because I never had it. It probably is good.

Popcorn: buttered or caramelized. 

Ohhh. Both! Ok. Butter…

Popcorn on stove or in microwave 

Microwave

Popcorn string: Make it yourself or purchase

Make it myself

Nuts-with or without shell

With shell.  I remember my grandmother brining walnuts & chestnuts over. Told us not to use the nutcracker, since it was good exercise to break with our hands. Not sure that made any sense :)

Peanut or cashews.

 WOW, Grandma must have had some strong hands! The only nuts I could crack open with my hand were peanuts and pistachios.

Cashews

Pumpkin or sunflower seeds?

The concept was to use one to break another. She didn't like technology. Used a wooden spoon to make mashed potatoes and whipped cream. Told my bother a blender ruined food. :)

Sunflower, though I'm not sure I could taste the difference. 

Granola or muesli. 

Granola (I am from Portland, lol ) You can use a blender to make mashed potatoes??? I use this funny metal doohickey thingy by hand, I thinks it’s called a potato masher

Mashed potatoes: add some sour cream when mashing or no

Yes, sour cream when mashing, stirring, mixing or blending.  Paul, your grandma was probably a wonderful cook!

I have made butter by whipping the crap out of cream. 

Raise your hands or yell going thru tunnel?

No, but I do hold my breath going through a tunnel

So that really works with making butter? 
 

Mashed potatoes: leave some skins on or no
