Place whole little potatoes in a large sauce pan and cover with water.

Bring to a boil and add the kosher salt then simmer 20-25 minutes until tender.

Reserve one cup of the potato water and drain the rest by pouring potatoes into a colander.

While potatoes are cooking, cut the dried peppers down the center from top to bottom, then discard seeds, stem and veins. Cut each pepper in half across the middle so you have four pieces per pepper. Set aside.

In a small saute pan over medium heat, melt 3 tablespoons of the butter and add the onion and garlic and cook until tender, about four minutes. Remove from heat and add in the dried pepper pieces.

Once the potatoes are cooked, pour off one cup of the water and put in the pan with the peppers and onion and cover tightly with a lid. Set your timer for 20 minutes.

After 20 minutes, puree the contents of the pan either in a blender or with an emersion blender. Set aside.

Heat a large non-stick saute pan over medium heat and melt the remaining two tablespoons of butter.

Add the cooked potatoes, salt and black pepper and cook and toss for five minutes until they start to brown.

Add the pureed liquid (the mixture will bubble and splatter), and continue to cook for another five minutes until the liquid starts to evaporate and thicken and coat the potatoes.

Serve topped with the crumbled Cotija cheese and chopped cilantro.
