2 potato color related questions in one post...
Got a 10lb bag of potatoes the other day, and almost half of them had large areas of green. Is it ok to cook/eat greenish potatoes?
Cut up fresh looking white potatoes into pieces and froze them immediately. A couple days later, they turned a rotten looking brownish color in the freezer! Am I doing something wrong?
Green potatoes indicated the production of solanine, which is a toxin very similar to cyanide. Though it may not make an individual sick right away, concentrations of it in the system, especially for sensitive individuals, can increase inflammation and aggravate things like arthritis.
Potatoes should be fully cooked before freezing for the best outcomes. Even then, they do better if frozen as pureed/riced potatoes (preferably with a little fat added) than as diced potatoes.
Raw baby potatoes IN their skin can be frozen with some success. Also, regular smooth-skin potatoes -can- be blanched for 3-5 minutes as cubes, and frozen, and will retain their white color, however, the texture will become mealy and they won't cook properly.
Since potatoes are a relatively quick prep (30 minutes or less) from fresh, I find it better to only buy as many as I'm going to eat in a given week, store them in a neutral-temperature or slightly cool, and very dark place, and then make sure I eat them within a week or two at most. I don't buy potatoes in bulk, and have actually stopped growing my own, since even a single plant produces far more potato than just the two of us can comfortably eat that quickly.
I always ate green potatoes my whole life. Waste not want not! It was only recently that I discovered they were supposed to be bad, but obviously, their toxins is not dangerous enough to cause serious probs for the average joe off the street. Still, no sense knowingly eating something that is unhealthful. Maybe you should just plant the green ones and play farmer for a bit! ;-P
As for the freezer thing, probably not a big deal. Lots of things turn diff colors when exposted to air for a short while.
I would like to ask a related question. When I buy organic white potatoes, lots of them have started to turn green or black. The conventional potatoes I can get are generally "prettier" with much less green and black spots. As potatoes are in the "dirty dozen" I try to get organic when I can, but is the additional solanine content rendering my efforts void? I always peel my potatoes well and boil them.
potatoes are night shade plants. they are found native to south america. paleo man never saw a potato. at least thats my thinking, correct me if im wrong because i am sure that white potatoes are not a paleo food.
