🥫 Storage and make ahead instructions

Let’s move on to practical tips to get the best results from your sourdough discard bread recipe.

  • The temperature of your kitchen can affect the rising time of your dough. Temperature control for rising is important. If your kitchen is cool, consider placing the dough in a warmed oven. Turn it off after preheating. Or place it near a warm spot in your house. This will give you a more consistent rise.
  • To get the best results, use the spoon-and-level method when measuring flour. Scoop flour into the measuring cup with a spoon and level it off with a knife. This prevents the flour from becoming compacted, which can lead to a denser loaf.
  • When handling sourdough discard, ensure it is at room temperature. Cold discard straight from the fridge can slow down the yeast activity and affect the rise of the dough.
  • Use a digital thermometer to check if your bread is baked and test for doneness. The internal temperature of the loaf should reach around 190°F (88°C). This is a more reliable method than tapping the bottom of the loaf for a hollow sound.
  • Slicing Tips: Resist the temptation to slice into the bread immediately after baking. Letting it cool completely on a wire rack allows the structure to set. This makes it easier to slice without crushing the loaf.
  • Once you’re comfortable with the basic recipe, feel free to experiment with flavors. Additions like herbs, cheese, dried fruits, or nuts can be interesting. This can add a new dimension of flavor and texture to your bread.

Storage Instructions

Storing your sourdough discard bread will help maintain its freshness and flavor:

  • Once completely cooled, store the bread in a bread box. Or, wrap it in a clean kitchen towel. Do this for up to 3 days. Avoid plastic bags, which can make the crust soft.
  • Refrigerating fresh bread is not generally recommended because it can dry out faster. If you must, wrap the bread in aluminum foil or a resealable plastic bag. It can last up to a week this way.
  • Freezing Instructions: To freeze the bread, slice it first if you prefer convenience. Wrap the whole loaf or individual slices in aluminum foil and then place them in a freezer bag. Squeeze out as much air as possible before sealing. Frozen, the bread will keep well for up to 3 months. Thaw at room temperature when ready to eat, or toast slices straight from the freezer.
  • Reviving Bread: If the bread becomes a bit stale, warm it in a 350°F (175°C) oven for about 5-10 minutes. This will refresh its texture and warmth. Remember, baked bread without preservatives doesn’t last as long as store-bought bread. It’s best enjoyed within a few days of baking.

Can i use active sourdough starter instead of discard?

Yes, you can use active sourdough starter. But, keep in mind that it will cause the dough to rise faster, so you may need to adjust the rising time or cut the yeast in half.

What if I don’t have instant yeast?

You can substitute instant yeast with active dry yeast. It might go a little slower, but it will be just fine. (You don’t have to proof active dry yeast!)

Will the bread be very sour?

No, the bread has a mild tanginess. The sourdough discard adds depth and flavor without overpowering sourness.

Do I need a stand mixer for this recipe?

No, a stand mixer is not necessary. You can knead the dough by hand, which may take a bit longer but is effective.

How can I determine if the bread is baked?

The bread is done when it reaches an internal temperature of around 190°F (88°C). You can also tap the bottom of the loaf; it should sound hollow.

Can I add other ingredients to the bread?

Feel free to experiment with additions like herbs, cheese, nuts, or dried fruits. They can add different flavors and textures to your bread.
