I used this recipe for week 31 of my food blog, "Travel by Stove." I am attempting to cook on meal from every nation on Earth, and Bhutan is my 31st stop. Unless otherwise noted, my Travel by Stove recipes are taken from authentic or traditional sources. This recipe does come from a Bhutanese source but is traditionally made with yak's cheese, which you can't currently get in the US. The substitute of feta and Danish bleu is considered an acceptable substitute if you can't get yak's cheese.
