I saw something about a Hot dog with a pretzel bun and got inspired. So I pretty much have the recipe close to where I want it. But not sure what to use as a wash. Tried egg whites so far and wasn't very happy. I'm open to all suggestions as I'm not sure what I want or what the expectation of a pretzel hot dog bun should be. Also would you doing anything special with the boil? Just using the standard baking soda and water at the moment. Thanks
You could get a better crust on the pretzels if you used baked soda instead of baking soda and it's still safer than playing with lye.
As for the wash... egg whites aren't going to give you much flavor. Did you try a regular egg wash? It will give the best color and shine. For flavor, though, you could try clarified butter or some sort of oil. You could mix it with spices or herbs - I brush oil and minced garlic on dough and bake it like that with nice results.
