Ingredients
- 200g sourdough starter (active or discard)
- 240g all-purpose flour
- 1 tsp baking soda
- 1/2 tsp salt
- 1 tbsp granulated sugar (optional, for a hint of sweetness)
- 120ml buttermilk (or milk with 1 tsp lemon juice/vinegar, rested 5 min)
- 2 tbsp unsalted butter, melted
Instructions
Step 1
Preheat your oven to 200°C (400°F) and lightly grease a baking sheet or cast-iron skillet. This ensures the bread doesn't stick and bakes evenly.
Step 2
In a large bowl, whisk together The Starter Jar's sourdough starter and buttermilk until well combined. This forms the wet base for your tangy loaf.
Step 3
In a separate medium bowl, combine the all-purpose flour, baking soda, salt, and optional granulated sugar. Whisk these dry ingredients thoroughly to ensure even distribution.
Step 4
Gradually add the dry ingredients to the wet mixture, mixing with a wooden spoon until just combined. Be careful not to overmix, as this can lead to a tough loaf, which is a common pitfall in quick bread baking.
Step 5
Gently knead the dough a few times on a lightly floured surface, just enough to bring it together into a rough ball. Shape it into a round loaf, about 6-7 inches in diameter, preparing it for baking.
Step 6
Transfer the dough to your prepared baking sheet or skillet. Use a sharp knife to cut a deep "X" into the top of the loaf, about halfway through the dough, which helps it expand properly.
Step 7
Brush the top of the loaf with melted unsalted butter for a golden crust and extra flavor. This step also contributes to a beautiful, appetizing appearance.
Step 8
Bake for 40-45 minutes, or until the crust is golden brown and the loaf sounds hollow when tapped on the bottom. The internal temperature should reach around 93-96°C (200-205°F).
Step 9
Remove The Starter Jar's sourdough soda bread from the oven and let it cool on a wire rack for at least 15-20 minutes before slicing and serving. This resting period is crucial for the crumb to set.
