filled my heart with red again

I have never claimed to understand potatoes, but I always thought I had colour figured out. Until the purple potatoes caught my eye at the farmer's market the other day.

It wasn't their regal hues that threw me off so much. I'm now quite used to seeing yellow radishes, green cauliflower, and a variety of other trendy tinted produce. What I was not expecting was what would happen when the potatoes hit the water.

As was perhaps only befitting to a St Patrick's Day dinner, as the purple potatoes began to boil, the water turned an increasingly brilliant green. I'm trying hard to remember my basic biochemistry and how it relates to the colour wheel as I know it, but an explanation for this phenomenon continues to elude me.

I welcome any and all explanations.

I don't know the science on that, but I bet it was quite a sight!

Obviously, you bought the potatoes of mass destruction.

Wandering Coyote said...

I am stumped.

my best guess is most tap water is slightly alkaline, which doesn’t jive well with the more acidic potato environment. Alas, the blue pigment (caused by the presence of antioxidants known as anthocyanins) left a green tint in your water.

Ok I didn't notice this I googled

know...not notice

This is amazing because purple is my favorite color and potatoes could possibly be my favorite food. I must find these!

It's a Saint Patrick's Day Miracle!

My self proclaimed "genius" son claims you merely "boiled the snot out of those potatoes."

I tell you Barb, it's like living with Jay Ingram.

It was astounding, Mr Anchovy, most fun I've had cooking dinner in a while.

It was all a nefarious plot, Dr M.

I was thinking I should save the water and tie-dye some shirts, WC.

You are some sort of google ninja, Kelly! It would have been nice if you could have also drawn us the Krebs cycle (complete with ATP involvement). That would have garnered you 100% on the exam.

Come visit me and I take you to my favourite farmers' market and buy you a bag, Beckeye. I will enjoy watching you explain them to airport security.

Must be the general lack of snakes in the area, Professor Chaos.

Please thank genius-boy for me, Sean, and let him know that he could be onto something, as I have always thought potatoes have a distinctly snot-like quality to their flavour. Also ask him if he could get Zia Tong's autograph for me.

kreb's cycle, shudder, I remember having to draw that on a biochemistry exam (what kind of idiot takes biochemistry as an elective?)

Barbara Bruederlin said...

There are no answers to that question, Kelly! Biochemistry was the scourge of my university career, the scourge!

And here I just thought this was your version of green beer. Thankfully, not.

How did they taste?

Barbara Bruederlin said...

No green beer (or facsimile) around this house, Al, never fear. I thought you might enjoy the purpleness of it all, though.

Despite their vibrancy, they tasted solidly ordinary, Leazwell, like a normal old potato.

Whenever I see purple potatoes like these I always think of the time when your mom and I planted some at a friend's farm. They very soon after got a pair of goats, and the potatoes became history as those little bastards will eat anything! (much to our chagrin!!)
