Day 320–Purple Mashed Potatoes

20121119-103008.jpg

Poor potatoes. For years, they were maligned as the source of all dieting evils. Eat a potato and you were sure to get a muffin top and diabetes. Maybe simultaneously. I never really liked potatoes all that much until I tried fresh, organic potatoes from Hill Top Farm. Those little potatoes are like a whole other food group. It made me realize how tasteless most grocery store potatoes are. Now, I have a new appreciation for them, although we don’t eat them a great deal.

I think that perhaps part of the potato problem is how we cook potatoes more so than the actual potato itself. Potatoes do have vitamins and minerals that are good for us, so why not? Fried potatoes, potato chips and potatoes slathered in gravy and/or cheese are not health food. If you buy good potatoes, though, you don’t have to do anything much at all for them to be amazing and satisfying.

We recently received some purple potatoes with our Produce Box, so I did some potato experimenting. I had never had purple potatoes before, but apparently the rest of the world loves them! These potatoes have flesh that is a deep bluish purple–mine were very dark. Purple potatoes are high in carotenoids, which offer some cancer protection. Carotenoids are not found in white potatoes. Early studies with purple potatoes also show a correlation between the dark potatoes and lower blood pressure.

For our cooking experiment, I quartered the first batch and roasted them with some olive oil and kosher salt. YUM! I did notice that like beets, the purple potatoes bleed their color. It’s a little disconcerting to look down and see your bluish hands!

Ellie and I decided to make purple mashed potatoes with the second batch. I was worried that the dark color would bleed out into the cooking water, leaving me with gray potatoes, so we boiled the potatoes whole (they were pretty small anyway) and mashed them with their skins on. The result? Cool looking purple mashed potatoes! We served them with a local pork roast and roasted local winter veggies!

Purple Mashed Potatoes

  • 2 lbs. or so of purple potatoes (go for the smallish ones)
  • 1/2 cup organic milk
  • 1/2 cup organic butter, melted
  • Kosher salt and pepper for seasoning
  1. Scrub potatoes, but do not remove the skins. Put potatoes in a large Dutch oven.
  2. Fill the Dutch oven with water to cover the potatoes by about 3″.
  3. Heat pot over medium high heat until boiling. Turn heat down if necessary and continue boiling potatoes for about 15 minutes. This will depend on how large your potatoes are, so check the potatoes and cook longer if needed. They should be very soft.
  4. Drain the potatoes and reserve 1 cup of the cooking water. Return the potatoes back to the pot and put the pot back on the stove eye that is cooling. Toss the potatoes around until they are fairly dry.
  5. Mash the potatoes with a masher. Add the butter and milk and mix together with a wooden spoon (you can also use an immersion blender for this). If the potatoes are too dry, add the reserved cooking liquid.
  6. Add salt and pepper to taste.
  7. Serve immediately!
