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

I don’t remember having different flavors of cotton candy.  We get a choice of pink or blue and I choose pink.

Hiking or biking?

Hiking, biking can be hazardous in the city.

Beach or mountains?

Regarding cotton candy, not sure the flavors taste different, but I've seen others.  I remember buying an Italian ice on the street years ago. The flavors were lemon, orange, chocolate, and blue. I asked the guy if blue was blueberry or mint, He said neither. I asked what the flavor was, he said blue. I told him blue was a color. He responded so is orange. I bought the lemon, but still don't know what blue tastes like. 

Java that story is hilarious! “Blue is a color…so is orange…” And after that you didn’t get the blue??? We all know what orange tastes like, but now I wanna taste blue too! Probably makes your tongue blue also just like those lollipops do 

Now that’s a tough tough choice…depends on my mood…(this is when I lick the tip of my finger and hold it up to the wind for a few seconds…) Beach it is! 
 

Build sandcastle or no 

Build, though it's been decades. 

Collect seashells or coins. 

Not a slushy fan so probably never tried anything blue. I was at a charity even sponsored by Absolut. Tried blueberry vodka, but that was still clear.
