Quickly add the almond flour mixture and the beaten egg to the melted cheeses. Mix to incorporate, then knead until smooth.

Divide the dough into 4 equal portions. Roll each portion into a thin 18-inch rope, then shape the rope into a pretzel.
Beat the egg yolk with a teaspoon of water to make an egg wash. Brush the tops of the pretzels with the egg wash and sprinkle them with coarse salt.

Notes
It's best to measure almond flour by weight. If you measure it by volume, make sure not to pack it into the measuring cups. It should be loosely packed.
Seasonings, especially salt, are guidelines. Adjust to taste.
If you have leftovers, it's best to freeze them in freezer bags and gently thaw them in the microwave. They don't keep very well in the fridge, but they do keep well in the freezer.
