U225X / ENGINEERING UNWARRANTED

Hot baking-soda pretzel bath

Public record / FOOD-010 / Revision A

PUBLIC RECORD
U225X

A dilute food-grade baking-soda bath changes the dough’s surface so it browns with a pretzel-like flavor. This is not a lye bath. New dilute simmer-bath option. King Arthur also documents a different hot-water soak; do not mix concentrations and times from different methods.

A RECIPE TO MAKEADDED TO THIS RECORD

This combines the measured FOOD-009 dough and FOOD-010 bath into one standalone recipe.

Added . This recipe addition is separate from the original notes below; it is not a claim of a tested batch.

Buttery pretzel bites with a hot soda bath

Adapted from the measured quantities already present in FOOD-009 and FOOD-010. The combined ingredient list and complete sequence are newly organized, with the existing formula preserved.

YIELD
About 48 bites
PREP / WAIT
25 minutes active; 45–75 minutes rising
COOK
12–16 minutes at 425°F

Ingredients

  • 1 cup (240 ml) warm water, 105–110°F
  • 2 1/4 tsp active dry yeast
  • 1 tbsp packed brown sugar
  • 3 cups (360 g) all-purpose flour, plus up to 2 tbsp as needed
  • 1 tsp fine salt
  • 2 tbsp (28 g) butter, melted and cooled, for dough
  • 6 cups water, for the bath
  • 1/4 cup ordinary food-grade baking soda, for the bath
  • 2 tbsp (28 g) butter, melted, for finishing
  • 1 tsp coarse pretzel salt, or to taste
  • 2 tsp neutral oil, for bowl and trays

Method

  1. Combine warm water, yeast and sugar and rest 5–10 minutes. Mix in flour, fine salt and the dough butter; knead 6–8 minutes until elastic, adding the extra flour only for persistently sticky dough.
  2. Place in a lightly oiled bowl, cover and rise 45–75 minutes until approximately doubled. Heat oven to 425°F and line two trays with lightly oiled, oven-rated parchment.
  3. Divide dough into four pieces. Roll each into a 12-inch rope and cut into 1-inch bites.
  4. Heat the bath water in a large pot and reduce to a gentle simmer. Add soda gradually, letting foam settle. Dip small batches for 20–30 seconds, turning once; drain with a slotted spoon and arrange spaced apart on the trays.
  5. Sprinkle with coarse salt and bake 12–16 minutes until well browned with cooked, springy centers. Rotate trays if they brown unevenly. Brush with finishing butter.

Notes & storage

  • This is the smaller FOOD-009/FOOD-010 formula; it differs from the large-pretzel batch in FOOD-008.
  • Serve warm. Store cooled bites airtight for 1 day or freeze for 2 months; reheat at 325°F for 5–8 minutes.
