One of my favorite cookbooks, King Arthur Flour Baker's Companion, has an excellent hot buttered pretzel recipe. I have never made something from this book which has not turned out well.
2 1/2 cups all purpose flour
1/2 teaspoon salt
1 teaspoon sugar
2 1/4 teaspoons instant yeast
1 cup warm water
1/2 cup warm water
1 tablespoon baking soda
3 tablespoons butter, melted
coarse salt of choice, kosher or pretzel
In a large mixing bowl, combine the water for dough, sugar and yeast, allow to rest 5 minutes.
Mix the water and baking soda in a small pan, warm and stir until most of the soda is dissolved and it is hot to the touch.
