I was so excited when I made my first sourdough starter! I watched the jar like a hawk, observing every millimeter of growth. I was obsessed and couldn’t wait to get started baking.

But as my starter began to grow, I quickly became overwhelmed. I didn’t quite know how to keep up with the feeding and discarding and soon my starter was out of control. I was producing more starter and levain than I knew what to do with.

My husband complained about the lack of room in the fridge because I had no less than 6 quart-sized containers of sourdough starter at various stages made with various flours.

And then, like all sourdough bakers, I realized I needed to discard and that sourdough discard is a valuable resource for any sourdough baker. It can be used to make delicious bread, brownies, waffles, and more!

Starter Vs. Discard

I’ll let you in a little secret. Sourdough starter and sourdough discard are the same darn thing!

Discard is simply an unfed sourdough starter that goes unused after a feeding. Sourdough starter is used to leaven bread while sourdough discard is, well, discarded.

It’s important to “discard” some of your starter after each feed, or you’ll become overwhelmed by the starter, like I was, because of the starter’s exponential growth. For example, if you start with a 50g starter and give it 50g each of flour and water, the next feed will have 150g starter and it will require 150g each flour and water, and the next feed will require 450g each, and the next feed….. *shudders*

Sourdough discard is easily distinguishable from starter by its texture. Starter is somehow light for its volume, and airy, and sticky, and bubbly. Sourdough discard is flat and runny, and dense because the yeasty beasties have consumed all the food.

Is Sourdough Discard Useful?

HECK YES!

You shouldn’t actually be discarding your sourdough discard! Discard is basically flour and water and flavor because it’s full of wild yeast and bacteria just like your starter, which means it can be used to make all sorts of delicious things!

While discard does not have the power to leaven bread it doesn’t mean it’s not useful to us, or that it can’t be used in baking recipes.

Discard can be used in bread recipes that call for yeast, it can be used in baked goods that rely on baking powder or baking soda for leavening, or it can be used in things that don’t require rising like cookies!

How To Store Sourdough Discard

Sourdough starter and discard should always be stored in a covered container that is NOT airtight, it is a fermentation after all and even if most of the food is consumed, a sealed container can cause pressure build up.

There are a couple of considerations to take into account when you’re trying to decide where to store your discard.

One thing to think about is when will you use the discard? Some methods are better suited for longer storage. Another consideration is the flavor. Different storage methods will affect the flavor!

Room Temperature:

The yeast and bacteria in sourdough discard work very quickly at room temperature, so I would only keep discard at room temperature IF you’re planning on using it within 1-2 days.

The cultures inside the discard will continue to consume remaining food and then start to die off and put out alcohols (hooch) and the flavor will quickly become overpowering.

There are no preparation steps to take when you’re using discard that’s been stored at room temperature, it’s ready to use when you are!

Fridge:

In my (un)professional opinion, storing sourdough discard in the fridge is the BEST way of keeping it.

I like to keep a quart-sized container in the fridge at all times for my discard, I just add to it every time I feed my starter, and it can be kept in there almost indefinitely. I mean, if something catastrophic happens, you could even use discard to revive your sourdough starter!

So while the fridge is cool and dark and it slows down yeast activity, we know from proofing sourdough in the fridge that it doesn’t completely stop fermentation or flavor development.

A discard kept in the fridge will have a slightly different flavor than a warmer discard. This is because the bacteria continue to break down available starches into lactic and acetic acid increasing the sour flavor.

I prefer to use my discard within 7 days of keeping it in the fridge, otherwise, you risk too much sour flavor!

To use sourdough discard that’s been stored in the fridge, place it on the counter to warm up for 2-3 hours before using.

Freezer:

If you’re baking a lot, or you get overtaken by sourdough starter cause you’re not discarding as much as you should, you can definitely toss some of that discard in the freezer.

Freezing is a great way to store sourdough discard for long periods of time (months!) without affecting the quality or flavor too much.

To use frozen discard, just pull it out of the freezer and let it thaw on the counter until completely thawed before using.

How To Use Sourdough Discard In Recipes

Now that you know how to store sourdough discard, let’s talk about how to use it in recipes! Using sourdough discard is a great way to add flavor and texture to all sorts of recipes, sweet or savory.

Here are some tips:

• Feel free to substitute discard into forgiving recipes, like sweetbreads and muffins. When I say forgiving, I mean a recipe that can handle a slight imbalance of liquid to flour, like my brown sugar banana bread.
• Avoid recipes that don’t have an obvious flour to liquid ratio, like cookies, unless they are written specifically to include sourdough discard, like my sourdough chocolate chip cookies.
• If you’re using a recipe measured by weight, subtract one-half of the weight of the starter from both the flour and water measurements.
• For recipes measured in cups and spoons, add in 120g of sourdough starter and subtract 1/2 cup of flour (60g) and 1/4 cup of water (60g).
