I forgot to mention an important fact about the potatoes. Green on the potatoes needs to be cut off. A lot of people don't know this but that is actually indicative of the presence of a toxin that the plants produce if the tuber (the potato, actually not a root but a tuber) is exposed to the sunlight. The chemical is toxic but take it from someone who has eaten his share of it, it takes a lot to make the average person sick. But don't take the chance and cut it out. All the green means is that the mulch we used didn't quite cover that particular potato. The rest is edible and you can just cut the green part out. Here is a link to information about the green you might find on some potatoes. http://www.snopes.com/food/ingredient/potato.asp
There are always some potatoes that don't get covered up. In the industrial, global 'food' system, they are discarded because they don't look right. In a local system, they are recognized for what they are, a good, hearty food that might require a little extra work to remove the part you don't want. Thanks for participating in the latter! Enjoy.
