History
Klondike and Nome gold rush prospectors so relied on sourdough starter that old-timers became known as 'Sourdoughs' across Alaska. Fire Island Rustic Bakeshop opened in 2009 and was named a 2026 James Beard Award finalist for Outstanding Bakery. Their crusty levain breads are the Anchorage benchmark.

Make it at home
Ingredients
- 100g active sourdough starter (100% hydration)
- 375g warm water (around 30C)
- 500g bread flour
- 10g fine sea salt
- Rice flour for dusting the banneton
Method
- Combine starter and water in a large bowl. Add the flour and mix to a shaggy dough. Rest 30 minutes.
- Add salt and a splash more water if needed. Mix until incorporated.
- Bulk-ferment at room temperature for 4-5 hours, doing 4 stretch-and-folds at 30-minute intervals in the first 2 hours.
- Shape into a tight ball, place seam-up in a rice-floured banneton and refrigerate overnight (12-14 hours).
- Preheat a Dutch oven inside a 245C oven for 45 minutes. Score the cold loaf and lower into the Dutch oven.
- Bake covered for 25 minutes, then uncovered for 20 minutes until deeply browned. Cool fully on a wire rack before slicing.
Tip from the editors. The cold overnight retard is the Alaskan trick. A long, slow second rise builds open crumb and develops the sour flavour without requiring summer warmth.
