    Zero Waste Guide to Managing a Sourdough Starter

    If you are wanting to maintain your sourdough starter with a zero waste sourdough discard routine, then this is the blog for you! Discard is essential to building a thriving sourdough starter, but you don't have to throw it away!

    If you are keeping your sourdough starter on your bench and feeding it regularly, you can accumulate a lot of discard quite quickly.

    A lot of people baulk at "discarding" half your starter every time you feed it, however it is a necessary part of the sourdough process. But just because you are removing the "discard" from your starter jar, doesn't mean you have to waste it.

    If you want to cut down on the amount of discard you produce, you can keep your mature starter in the fridge - but even then, you will still have a bit of discard to deal with.

    You could also maintain a much smaller starter and then build what you need each time you bake.

    But half the fun of maintaining a sourdough starter is finding creative ways to use the discard, right?

    IMPORTANT NOTE - I advise not to use your sourdough discard for the first 5 to 7 days of building your sourdough starter. During this time the good bacteria are fighting it out for dominance and the yeast colonies are still being established. It usually smells really bad in these first few days. Put this early discard into the bin or compost.

    Zero Waste Sourdough Discard

    There are lots of interesting and delicious ways to use your sourdough discard instead of tossing it in the bin. Here are 17+ uses that will ensure your sourdough starter is never wasted.

    Dry Your Sourdough Discard

    There are so many uses for dried sourdough starter discard, many of which you probably haven't thought of. Now remember discard is unfed starter that you are removing from the jar when you go to feed it.

    Take your discard and smear it onto some baking paper and let it dry on your kitchen bench or even in a dehydrator at a low temperature (it really doesn't take long). Once the discard is completely dry, blitz it in a high powered food processor (I use my Thermomix). Now you've got a nutrient rich, probiotic filled powder that you can use for a variety of purposes:

    • Use it as "flour" and add to cakes, muffins, pizza - even your bread!
    • Use it as a crunchy topping for salads, pasta or soup
    • Add it to your breadcrumbs for crumbing chicken or fish
    • Use it as a delicious crunchy topping for roast potatoes
    • Mix it with some nutritional yeast to make vegan parmesan
    Zero waste sourdough discard - dry your discard in a dehydrator to create a tasty addition to salads, vegetables or bread.
    Shards of dried sourdough discard - to speed up drying process, break up the pieces as they dry so that they get smaller and smaller. Once fully dried, they're ready to blitz!

    Make a Sourdough Discard Batter

    Traditional batter is just flour and water ... and isn't that what sourdough discard is? So it makes sense to use your discard as a batter! There are a few ways you can jazz it up.

    To use your sourdough starter as batter, add ¼ teaspoon of baking soda to 100g of discard. Give it a mix and add any flavourings you might like - then coat your food and fry. If you want to make your batter go a little further, you can add a little soda water and extra flour - whisk with a fork until it's like runny pancake batter.

    You could add a little curry powder to some batter and fry fish. A little cinnamon and fry some banana. Paprika could be a good addition to chicken.

    Sourdough Discard Tortillas

    Tortillas have become a very popular part of many household's everyday cuisine. While they are relatively inexpensive to buy - you seriously cannot top the texture and flavour of making your own, especially when you add some sourdough discard into your dough.

    You will not be disappointed!

    Fresh Pasta Made From Sourdough Discard

    Another less known way to ensure you have zero waste sourdough discard is to make wholesome fresh pasta with it.

    You'll need 215g 00 flour, 1 large egg & 2 large egg yolks and around 175g discard.

    You can either roll the pasta dough out by hand or use a pasta machine.

    Make your pasta as per normal, incorporating the eggs and discard into the dry flour. If it's too wet, just add a little more flour.

    This is a delicious and slightly unusual way to use your discard.

    You can even dry your pasta for later use.

    Sourdough Discard Bread

    There are lots of different names for this bread - some people call it a "cheat's sourdough" others discard bread.

    I just call it delicious!

    It's super easy and enables you to get a loaf of bread on the table FAST, while still utilising your starter.

    You'll need to add a little commercial yeast to get this bread bubbling, but don't be disheartened, it's going to make you come back for seconds, I promise! You'll find the recipe for sourdough discard bread here.
