1 c. warm water
2 1/2 to 3 c. flour*
2 T. oil
1 T. sugar
6 T. baking soda in 6 cups water
*I use about 1/4-1/3 amount of whole wheat flour.
I always double this recipe. We can eat 12 pretzels really fast, so I make two batches and put some in a Ziploc in the freezer once cooled. The one time I only made one batch it was very disappointing and hardly worth the effort. I use 9 T. baking soda in 9 c. water when I make two batches.
This is a fair amount of work, but worth it if you love soft pretzels. They don't have the fake aftertaste of the store-bought ones and the cost works out to be less than 6 cents per pretzel!
In a bowl, dissolve yeast in water. add 1 1/2 c. flour, the oil, and the sugar. Beat for about 3 minutes to make a smooth batter. Gradually stir in enough of the remaining flour to form a soft dough. Turn out onto a floured board and knead until smooth and satiny (about 5 minutes) adding flour as needed to prevent sticking. Place dough in a greased bowl, turning to grease top, and cover and let rise until double (1 hour).
