Preheat oven to 300°F. Spread baking soda on a foil lined sheet pan and bake for 1 hour. Whisk into 4 cups cool water until dissolved. Increase oven to 400°F.

In a large bowl combine self rising flour and brown sugar. Add Greek yogurt and stir until a shaggy dough forms.

Turn dough onto a lightly floured surface and knead for 1 to 2 minutes until smooth. Let rest for 15 minutes.

Divide the dough into 8 equal pieces. Roll each piece into a rope about 15 to 18 inches long.

Form into a "U" shape with the ends pointing away from you on the counter.

Cross the ends over each other about 2 inches down their length.

Twist them once.

Fold back down onto the bottom curve and press gently to adhere.

Dip each pretzel in the baking soda wash for 15 to 20 seconds per side.

Place on parchment lined baking sheet and sprinkle with pretzel salt.

Bake at 400°F for 20 to 25 minutes until deeply golden brown.

Brush or spray with melted butter while warm for classic mall pretzel flavor.
