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

Oh yeah, there’s that one too!  Yes it does, but it has a different texture. My friend’s mother, when I was in high school, always engaged us in different cooking skills that weren’t used much anymore.  We even pulled taffy once!

No skins.

Favorite taffy flavor?  Mine is cinnamon

Watermelon. Can't say I eat taffy unless I'm in Atlantic City.

Favorite cotton candy flavor
