Navajo Coffee is coffee that has been thickened with toasted flour. In fact, it’s so thick it’s like a paste and you can eat it with a spoon.
The coffee uses a very specific flour, called Blue Bird flour, made by the Cortez Milling Company in Cortez, Colorado, which is popular in the south-west. Blue Bird is also a favoured choice for making Navajo Fry Bread and Tortillas.
It contains about 7% protein, less than all-purpose flour (10-11%), so it has a lower gluten content making for a lighter, chewier bread. The flour is toasted in a cast-iron skillet and then added to the coffee to thicken it. Sugar is added for sweetness.
