01 - Combine active sourdough starter and warm water in a large mixing bowl. Stir until completely dissolved and homogeneous.
02 - Add bread flour, granulated sugar, salt, honey, chopped pistachios, and freeze-dried raspberries to the starter mixture. Mix thoroughly until a shaggy, uneven dough forms.
03 - Transfer dough to a lightly floured work surface. Knead vigorously for 8 to 10 minutes until the texture becomes smooth, elastic, and properly developed.
04 - Place dough in a lightly oiled bowl. Cover and ferment at room temperature for 8 to 12 hours, preferably overnight, until doubled in volume.
05 - Turn fermented dough onto a flour-dusted surface. Divide into 8 equal portions. Roll each portion into a smooth ball.
06 - Poke a hole through the center of each dough ball. Gently stretch and widen the opening to create the classic bagel ring. Arrange on a parchment-lined baking tray.
07 - Cover the shaped bagels and let rest at room temperature for 45 to 60 minutes until slightly puffed and visibly expanded.
08 - Preheat oven to 425°F. In a large pot, bring the poaching liquid to a steady simmer.
09 - Carefully drop bagels into simmering water in small batches. Poach for 45 seconds per side. Remove using a slotted spoon and return to the prepared tray.
10 - Immediately sprinkle the poached bagels with additional chopped pistachios and freeze-dried raspberry pieces while the surface remains tacky.
11 - Bake for 20 to 22 minutes until deep golden brown and fully cooked through. The crust should be firm and glossy.
12 - Transfer bagels to a wire cooling rack. Allow to cool completely before slicing or storing.
