Brezel (Pretzel)

Bavarian Laugenbrezel (Lye Pretzel)

The classic Bavarian pretzel: a yeasted dough shaped into a knot, dipped briefly in food-grade lye for its glossy mahogany crust and signature tang, then baked until chewy inside and crisp outside. In Germany a Brezel at breakfast, with butter and a cold beer, or straight from the Bäcker is everyday food.

Recipe ingredients

• •500 g (17½ oz (about 4 cups)) bread flour, high-protein flour gives the classic chew; all-purpose works in a pinch
• •10 g (2 tsp) fine sea salt, for the dough
• •7 g (1 packet (2¼ tsp)) instant dry yeast, or 20 g fresh yeast
• •30 g (2 Tbsp) unsalted butter, softened
• •250 ml (1 cup + 1 Tbsp) lukewarm milk, about 38 °C / 100 °F
• •60 ml (¼ cup) lukewarm water, about 38 °C / 100 °F
• •40 g (about 3 Tbsp) food-grade sodium hydroxide (NaOH) pellets, also called 'Ätznatron' in Germany. CAUSTIC - do not substitute with baking soda for authentic results. Handle with gloves and goggles. See safety note below.
• •1000 ml (4 cups) cold water, for the lye bath
• •30 g (about 3 Tbsp) coarse pretzel salt, or flaky sea salt; not table salt
• •30 g (2 Tbsp) melted butter, for brushing after baking, optional

Steps

1. 1 SAFETY FIRST: Sodium hydroxide (lye) is caustic. Wear rubber gloves and eye protection. Work near a sink with running water. Keep white vinegar nearby to neutralize any splashes on skin. Do not use aluminum - lye reacts with it. Keep the solution away from children and pets. Never use food-grade lye substitution (drain cleaner) without confirming it is 100% pure NaOH.
2. 2 Make the dough: In a large bowl (or stand mixer with dough hook) combine flour, salt, yeast, softened butter, milk and water. Knead for 8-10 minutes until smooth, elastic and only slightly tacky. The dough should not stick to clean hands.
3. 3 Shape into a ball, place in a lightly oiled bowl, cover and let rise at room temperature for 45-60 minutes, until roughly doubled.
4. 4 Divide the dough into 8 equal pieces (about 105 g each). Roll each piece on an unfloured surface into a rope about 50 cm / 20 in long, tapering slightly at the ends.
5. 5 Shape each pretzel: form a U with the rope, cross the ends over each other twice in the middle, then lift the crossed ends down and press them onto the bottom curve of the U at roughly the 4 and 8 o'clock positions. Place on parchment-lined trays, cover loosely and rest 15-20 minutes.
6. 6 Meanwhile, prepare the lye bath: put on gloves and goggles. In a stainless steel or glass bowl, dissolve 40 g NaOH pellets in 1000 ml cold water - always add lye to water, never water to lye. Stir with a wooden or plastic spoon until fully dissolved. The solution will feel slippery and is caustic - do not touch with bare skin.
7. 7 Chill the lye solution in the freezer for 15-20 minutes until it is cold but not frozen. Cold lye gives better color and a thinner crust.
8. 8 Preheat the oven to 230 °C / 450 °F (conventional) or 210 °C / 410 °F (fan). Line two trays with parchment paper (parchment is essential - the lye will eat other surfaces).
9. 9 Using gloves, dip each pretzel into the cold lye bath for 3-4 seconds per side, drain briefly, then return to the parchment-lined tray. Work with one or two pretzels at a time so they do not sit wet.
10. 10 Immediately sprinkle generously with coarse pretzel salt, pressing the crystals gently into the wet surface so they adhere.
11. 11 Bake on the middle rack for 12-15 minutes, turning once halfway, until deep mahogany brown. Do not underbake - pale pretzels are gummy. Internal temperature should reach at least 93 °C / 200 °F.
12. 12 Transfer to a wire rack. Brush lightly with melted butter while still warm if you want a soft, glossy crust (traditional Bavarian style).
13. 13 Cool at least 10 minutes before eating. The crust will crisp as it cools. Eat the same day, ideally within a few hours of baking. Lye residue is neutralized by baking; the finished pretzel is safe and only slightly tangy.
14. 14 Baking soda shortcut: if you cannot obtain food-grade lye, dissolve 80 g baking soda in 1 L boiling water and dip pretzels for 30 seconds. The color and flavor will be noticeably milder and more biscuity, not the deep mahogany and tang of an authentic Laugenbrezel - note this substitution in your result.
