Sourdough Starter in 6 days

With yeast being a little difficult to find at the moment (during Covid-19 lockdown), we thought we’d have a go at making a new (and unusual) quick sourdough starter. If you love making sourdough bread, but your sourdough starter is no more, you might be interested in this…

What if you could have a new sourdough starter up and running in just 6 days? This starter is weak at the start, but it matures way faster than your usual flour and water kind. Why, you ask? keep reading.

I was looking through some old pastry chef notes from years ago and found something I hadn’t tried but thought sounded interesting at the time. Using yoghurt to build a sourdough starter. Yep, you heard me.

I make my own yoghurt, and a lot of my students do too because they’ve done one of my courses or they’ve seen this post. For this starter, use real yoghurt made with a yoghurt strain, not yoghurt made with a probiotic capsule. Or purchase a plain pot set of yoghurt. Nothing with flavours in it.
So if you’ve made sourdough before and want to get a starter up and running faster, try this method for a yoghurt sourdough bread starter. You can use it with any sourdough recipe. Just remember it’s weak at the start, and you will need to give it some strength. But it will develop way faster than a normal starter because you’ve added the culture it needs instead of waiting for the universe to provide. 🤣🤣🤣
I use this starter now with the overnight sourdough method I’ve shared in my Easy Overnight Sourdough Course. This is a method that’s similar to a bakery method that I’ve developed so It can be made at home on a smaller scale. You can have sourdough bread every day if you choose. It’s that simple.

My wonderful Bake Club and sourdough students inspired me to develop this new method. I asked a few of them, “What would be important to you when making Sourdough bread?” They came back with a list of wants and needs.
Here are the main points
- Easy
- Have less discard and don’t have to keep much in the jar.
- Can I make my bread without kneading?
- Easy feeding instructions that don’t require daily attendance
- Less mess
- Be able to make it at the weekend.
- I’d rather it make itself while I was asleep. (very funny, Angela. But I got ya. LOL)
I loved working on this. I want to thank Angela, Sally, Christine, Anne-Marie and Wayne for being my editors, method testers and taste testers. Adapting a bakery method into a method that can be made on a small scale was fun.

Bec’s Yoghurt Sourdough Starter
5 stars tells us you love the recipe
becs-table.com.auEquipment
- 1 1 litre jar
Ingredients
- 20 g skim milk powder Skim milk powder
- 160 g cool boiled water I just grab it from the jug
- 80 g Pot set yoghurt No flavour/No sugar
- 500 g Plain flour plain works well; it doesn't need gluten here.
Instructions
- Day 1 Sterilise your 1 litre jar. I do this by washing and rinsing really well. Dry the outside with a t-towel and pop it in the microwave. set it for 5 seconds. Yep with nothing in it but the little bit of water that remains from rinsing.
- Weigh the yoghurt and milk powder into the jar and mix well to combine. Then weigh in the water and mix again.
- Pop the lid on the jar and sit it in a bowl. Pour enough hot tap water in the bowl for the water to come up to the same mark as the liquid inside. We don't want boiling water here, just hot enough to gently warm the liquid inside to start the process. Now set this aside in a warm place for 24 hours

- Day twoYou may notice that the liquid inside has separated a little, don’t worry, it's fine. Remove thelid and weigh in 120 g bakers flour and mix well with a fork. I use a fork because you want to try and create some air bubbles if you can. I also chose a fork that will fit inside my jar with the lid on. Lazy I know. 😉 Now set the jar aside in a warm place for 2 whole days.
- Day fourRemove the lid and weigh in more flour 135g and cool boiled water 135g, mix again with the fork. Leave until tomorrow
- Day fiveThis is the first time and only time you should need to throw some starter out. It's only because we need to fit more in the jar. (You could add it to another jar and have two going I suppose or use it in pancakes or the like ;-))You should now be seeing signs of life, loads of tiny bubbles throughout your starter. Remove 1/2 the starter from the jar and weigh in another 130 g flour and 130 g water and mix.set aside until tomorrow.
- Day sixToday's the day you can make your first loaf. Go on, what are you waiting for? Use this starter with a pinch of dried yeast for a month or two while it builds its strength. Hey, I said a pinch no more. 😉oh, you want a recipe?

Want to know more?
I’ve got another recipe on my site that uses sourdough or a poolish that you can make really quickly. French baguettes. I don’t consider it a proper sourdough because it hasn’t had the benefit of a lengthy fermenting process. But they’re so good and easy to make.

Ok thanks for the info I’ll wait till I can get skim milk powder
Regards Carol
no worries Carol
Hi Bec, I want to give your starter a go, never done any starter before, I only have full cream milk powder, will it still work?
Regards Carol
I haven’t tried making this starter with full‑cream milk powder, and I wouldn’t recommend it. The starter really doesn’t need the added fat — it’s there for the natural sugars and proteins from the milk solids, and extra fat could change its composition quite a bit.
Just keep in mind that this starter will be quite weak in the beginning. It’s designed as a bit of a “head start” method, so while a traditional flour-and-water starter can take two to three months to really strengthen, this one should be ready in about a month instead.
Have a read through the whole post before you start — it’ll make a lot more sense once you see how it all comes together.
Hi, I was planning on giving this a go I have full cream milk powder will it matter or do I need to switch it for skim.
