What did I learn from this recipe?
I had forgotten to get the sour cream for these the last time I was at the store. But, I had a jar of salsa Verde instead and these tacos actually needed the extra spice (I also added a little minced garlic to the potatoes). I think with sour cream, these tacos would have been like shoving a cloud into your mouth: mealy and soft. There was really nothing to set the various flavors apart, save the salsa. It was a lot like a bean burrito.
