Blot the hot dogs dry with a napkin, pierce with a bamboo skewer.
Combine all dry ingredients in one bowl. In the other, beat the buttermilk and eggs with a fork. Combine both mixtures and whisk until smooth.Let the dough stand for about 5 minutes, then pour into a tall glass. In the meantime, heat enough oil in a deep skillet to 375F.
Dip the hot dog into the dough, place in hot oil. Cook 3 to 5 corndogs at a time for about 4 minutes, turning if necessary until golden brown.
Place the corndogs on a paper towel, garnish with the sauce and serve.
