01 - In a large bowl, mix the sourdough starter and warm water until dissolved.
02 - Add bread flour, sugar, salt, honey, pistachios, and freeze-dried raspberries. Mix until a shaggy dough forms.
03 - Knead the dough on a lightly floured surface for 8-10 minutes until smooth and elastic.
04 - Place the dough in a lightly oiled bowl, cover, and ferment at room temperature for 8-12 hours or overnight until doubled in size.
05 - Turn the dough onto a flour-dusted surface and divide into 8 equal pieces. Shape each piece into a ball. Poke a hole through the center of each ball and stretch gently to form a bagel shape.
06 - Place shaped bagels on a parchment-lined tray, cover, and let rest for 45-60 minutes until slightly puffed.
07 - Preheat oven to 425°F. Bring the poaching liquid to a simmer in a large pot.
08 - Gently drop bagels into simmering water in batches; poach for 45 seconds per side. Remove with a slotted spoon and return to tray.
09 - Sprinkle bagels with additional chopped pistachios and freeze-dried raspberry pieces if desired.
10 - Bake for 20-22 minutes until golden brown. Cool on wire racks before serving.
