Make-Ahead Instructions
To ensure our sourdough bialys develop optimal flavor and texture, planning ahead is key. Here’s how we can prepare the dough and onion filling in advance to streamline the baking process and deepen the complexity of flavors.
Prepare the Dough Ahead
- Mix and Knead
Combine all dough ingredients as outlined, kneading until smooth and elastic. This initial step sets the foundation for our chewy, tangy bialys.
- Bulk Fermentation in the Refrigerator
Transfer the dough to a lightly oiled bowl, cover tightly, and refrigerate for 12 to 24 hours. The slow fermentation enhances the sourdough character and improves dough strength.
Tip: A longer cold ferment develops richer flavor but avoid exceeding 48 hours to maintain dough quality.
- Shape and Proof the Bialys Next Day
Remove the dough from the fridge and allow it to come to room temperature for about 1 hour. Shape into individual bialys, creating the signature indentation for the onion filling. Proof on a parchment-lined tray, covered, for 1 to 2 hours until noticeably puffy.
Make the Onion Filling in Advance
- Sauté Onions
Gently sauté finely diced yellow onions in olive oil with salt, pepper, and optional dried minced garlic until caramelized and fragrant. This base will infuse each bialy with savory richness.
- Cool and Store
Let the filling cool completely, then transfer it to an airtight container. Store it in the refrigerator for up to 3 days.
- Add Poppy Seeds Before Baking
For freshness and texture, sprinkle toasted poppy seeds on top of the onion filling just before filling and baking the bialys.
| Step | Action | Time Frame | Storage |
|---|---|---|---|
| Dough mixing & kneading | Combine ingredients, knead | Preparation day | |
| Bulk fermentation | Refrigerate dough | 12 to 24 hours | Covered bowl in fridge |
| Onion sautéing | Cook onions with seasoning | Preparation day | Airtight container in fridge |
| Dough resting (temp) | Bring dough to room temp | 1 hour | Covered |
| Shaping & proofing | Shape and proof dough | 1 to 2 hours | Covered tray |
| Onion filling topping | Add poppy seeds | Just before baking |
By organizing our workflow with these make-ahead instructions, we unlock convenience without sacrificing the hallmark texture and flavor of authentic sourdough bialys. This preparation strategy makes baking day smoother and allows us to focus on perfecting the final bake.
Instructions
Follow these precise steps to craft authentic sourdough bialys with a tender crumb and savory onion filling. Each phase builds on the previous to develop flavor and texture, guiding us toward perfect results.
Preparing the Sourdough Starter
- Ensure your active sourdough starter is bubbly and refreshed within the last 6–8 hours.
- Feed the starter with equal parts flour and water by weight (e.g., 50g flour, 50g water).
- Maintain a consistency similar to thick pancake batter for ideal fermentation.
- Allow the starter to ferment at room temperature until it visibly doubles and shows numerous small bubbles.
Making the Dough
- In a large mixing bowl, combine the following ingredients:
| Ingredient | Quantity | Notes |
|---|---|---|
| Active sourdough starter | 150g | Prepared as above |
| Bread flour | 400g | Preferably high-protein flour |
| Water | 250ml | Room temperature |
| Fine sea salt | 10g | For flavor |
| Honey | 15g | Enhances browning and flavor |
| Olive oil (optional) | 15ml | Adds tenderness |
- Mix all ingredients gently with a dough whisk or wooden spoon until a shaggy mass forms.
- Turn the dough onto a lightly floured surface and knead for 8–10 minutes until smooth and elastic.
- If the dough feels sticky, dust with small amounts of flour gradually. Avoid adding too much to maintain moisture.
First Rise
- Place the dough in a lightly oiled bowl and cover with a damp cloth or plastic wrap.
- Allow the dough to ferment at room temperature for 4–6 hours until it has expanded noticeably but not fully doubled.
- For a more complex flavor, conduct a cold bulk fermentation by refrigerating the dough for 12–24 hours—this enhances tanginess and texture.
Shaping the Bialys
- Gently punch down the dough to release gas without deflating it completely.
- Divide the dough into 10 equal portions (approx. 80–90g each).
- Shape each piece into a smooth ball by pulling and tucking the dough underneath.
- Place the dough balls on parchment-lined trays spacing them about 2 inches apart.
- Using your fingers, press a shallow indentation (~2-inch diameter) in the center of each ball to create the characteristic bialy cavity.
Adding the Filling
- Prepare the onion filling by sautéing finely diced yellow onions in olive oil until golden and caramelized.
- Mix in toasted poppy seeds, coarse sea salt, freshly ground black pepper, and optional dried minced garlic.
- Spoon the cooled onion mixture generously into each indentation, pressing lightly so the topping adheres without spilling over.
Second Rise
- Cover the bialys loosely with a clean towel or plastic wrap.
- Allow them to proof for 1.5–2 hours at room temperature until puffed and airy but not overly soft.
Baking the Bialys
- Preheat your oven to 475°F (245°C) with a baking stone or steel on the middle rack for at least 45 minutes to ensure thermal mass.
- Slide the parchment with bialys directly onto the hot stone or steel.
- Bake for 12–15 minutes until the crust is deep golden brown and the edges crisp.
- Remove from oven and cool on a wire rack for 20–30 minutes before serving to set the crumb and filling.
Pro Tip: For an extra crusty exterior, mist the oven with water immediately after placing the bialys inside to generate steam.
