In a large mixing bowl, combine the active The Starter Jar sourdough starter, warm water, and barley malt syrup (if using in dough). Whisk until mostly dissolved.
Add the bread flour and fine sea salt to the wet ingredients. Mix with a spoon or your hands until a shaggy dough forms and no dry spots remain.
Cover the bowl with a damp cloth or plastic wrap and let it rest for 30 minutes. This allows the flour to fully hydrate.
Turn the dough out onto a lightly floured surface. Knead for 8-10 minutes until the dough is smooth, elastic, and passes the windowpane test. Alternatively, use a stand mixer with a dough hook for 6-8 minutes on medium speed.
Place the dough in a lightly oiled bowl, cover, and let it ferment at room temperature (70-75°F / 21-24°C) for 2-4 hours, or until it has increased by about 20-30% in volume. Perform one set of stretch and folds after the first hour.
Gently turn the dough onto a lightly floured surface. Divide the dough into 8-10 equal pieces (around 80-90g each). Roll each piece into a tight ball, then create a hole in the center with your thumb and gently stretch it to about 1.5-2 inches in diameter.
Place the shaped bagels on a parchment-lined baking sheet, ensuring they have space between them. Cover loosely with plastic wrap and refrigerate for 8-12 hours, or overnight. This slow proof develops complex flavors and aids in texture.
The next morning, preheat your oven to 450°F (230°C) with a baking stone or inverted baking sheet inside. Bring 2 liters of water to a rolling boil in a wide pot, then add 2 tbsp barley malt syrup (or baking soda) and 1 tsp salt.
Gently drop 2-3 bagels into the boiling water, ensuring they don't overcrowd the pot. Boil for 30-60 seconds per side for a chewier bagel, or 90 seconds per side for an even chewier, denser result.
Remove the boiled bagels with a slotted spoon, letting excess water drain. Place them back on the parchment-lined baking sheet. Immediately sprinkle with desired toppings while still wet.
Carefully transfer the bagels to the preheated oven. Bake for 18-25 minutes, rotating halfway through, until they are golden brown and cooked through.
Transfer the baked bagels to a wire rack and let them cool completely before slicing and serving. This allows the interior to set properly.
