Spending a Saturday night baking this sourdough sandwich bread was such a rewarding and enjoyable experience. Using sourdough discard not only adds a rich, tangy flavor to the bread but also reduces waste, which is a win-win for both taste and sustainability. I found that mixing active yeast with the starter discard accelerates the rising process, making it a great option when you want fresh bread without the long fermentation time typical of traditional sourdough. When following the recipe, make sure your water is warm but not hot, as too high a temperature can kill the yeast. Dissolving the sugar first helps to activate the yeast faster, giving your dough a good start. Using bread flour is key here because it has a higher gluten content compared to all-purpose flour, resulting in a better structure and chewiness essential for sandwich bread. Kneading the dough in a stand mixer with a dough hook saves time and effort, ensuring the dough develops enough gluten for a good rise. After shaping your loaf and placing it into a greased pan, letting it rise for about an hour allows the dough to double in size, which is crucial for a light, airy crumb. Baking at 350°F for 25-35 minutes yields a beautifully golden crust that’s soft but sturdy enough for sandwiches. I recommend checking your bread with a toothpick or tapping the bottom of the loaf—it should sound hollow when fully baked. Using this sourdough sandwich bread recipe made from starter discard is a great way to keep your baking sustainable while still enjoying homemade bread packed with flavor and texture. Plus, it’s a comforting way to spend a Saturday night with a fun, hands-on kitchen project.
