01 - Combine active sourdough starter with warm water in a large mixing bowl. Stir until completely dissolved and smooth.
02 - Add bread flour, sugar, salt, honey, chopped pistachios, and freeze-dried raspberries to the starter mixture. Mix thoroughly until a shaggy, rough dough forms.
03 - Turn dough onto a lightly floured surface and knead for 8 to 10 minutes until smooth, elastic, and fully developed. The dough should spring back when pressed.
04 - Place dough in a lightly oiled bowl, cover with plastic wrap or a damp towel. Ferment at room temperature for 8 to 12 hours overnight until doubled in size.
05 - Turn fermented dough onto a flour-dusted surface. Divide into 8 equal portions. Shape each piece into a smooth ball by tucking edges underneath.
06 - Poke a hole through the center of each dough ball using your finger. Gently stretch and rotate to create an even ring. Place on parchment-lined baking sheet, cover, and rest for 45 to 60 minutes until slightly puffed.
07 - Preheat oven to 425°F. Bring poaching liquid to a gentle simmer in a large pot—water should not be boiling vigorously.
08 - Gently drop bagels into simmering water, working in batches of 2 to 3. Poach for 45 seconds per side. Remove with slotted spoon, drain briefly, and return to parchment-lined tray.
09 - Immediately sprinkle poached bagels with chopped pistachios and freeze-dried raspberry pieces while surface is still tacky. Press gently to adhere.
10 - Bake for 20 to 22 minutes until deeply golden brown with a glossy, crackled crust. Rotate tray halfway through for even coloring.
11 - Transfer baked bagels to wire rack and cool completely before slicing or serving—at least 30 minutes for proper texture development.
