Once your starter is alive and active it only needs to be fed when you want to use it.
Store your starter in the fridge with a fitted lid on in between uses. Your starter stays happily dormant in the fridge, you will see just how magic it is when you take it out of the fridge and it looks sludgy and dull, and then it comes up to room temperature and you feed it and it bounces back.
My Star, above, for the fridge after a few days lying dormant
After feeding and leaving her to do her work, she’s all bubbly an active and ready to go, as the photo at the top of the page shows. This may take 2-3 hours in the summer, or 4-5 hours in the winter, your room temperature will have a big effect on how your starter behaves and responds. Warmth will speed it up, cold will slow it down. Watch your starter and see how it behaves for you in your environment, and take a note of its activity, the temperature and timings for future reference,
It truly is hypnotic, you can see why people fall in love with sourdough, and why some people get a bit obsessive about their starters.
As time goes on, you will get a feel for your starter and how strong it is. You will realise that if you forget to feed it for a couple of weeks, it can still be nurtured back to life. If you’re going to be away for many weeks or months, you can feed it up, get it bubbly and active, and dry it out on parchment paper and store it in a jar until you’re ready to reactivate it.
And the most important part of keeping a starter: give it a name! Mine is called Star.
What you need to know about your starter…
There is a short window of time when your starter is as its peak and ready to use. It should be a lovely glutinous consistency, with a thickness like a thick mini pancake batter, and full of bubbles as you stir it. If it has gone past this point it will be flat and lifeless which doesn’t mean it’s dead, it just means it needs to be fed to bring it back up to its optimum strength.
In between feeds, whilst your starter is in the fridge, it becomes dormant and sometimes it will look like it’s separated, with a layer of murky liquid on the top often called the ‘hooch’. This is absolutely normal. Just stir it all back together again and use the starter as required.
Only ever keep about 100-150g of starter…
You don’t need any more starter than that, keeping your starter lean enables you to feed the whole starter every time your use it, which helps it make it stronger and stronger with every use.
If you try and keep more it will become slow and sluggish and inactive.
If you’ve got more happy bubbly starter than you need on that day, you can make another loaf, use it in other recipes, dry it out and gift it someone else, or merely discard it.
Don’t change the bowl…
Your starter lives happily in the bowl or jar in which you made it, it does not need to be cleaned and changed, if it’s happy where it is, leave it, don’t disturb it. The bowl does not need to be spotless or pristine, it’s a working vessel. Any dried flour or starter up the sides of the bowl is all good extra power, scrape it off and stir it in.
The ONLY time that the bowl needs changing, or indeed that your starter is at risk, is if it develops mould. In this case, your starter is lost and you will need to make a new one in a clean bowl.
What is ‘discard’?
When you read about sourdough and starters, you will see a lot of discussion about starter ‘discard’; this is the name given to the excess of starter that is generated when making a starter, or from the process of feeding it. It’s basically means the extra, and if you do generate more than you need, there are lots of recipes for using it in different ways, including some on my blog.
I never have any discard because I keep a base amount of starter that is sufficient to feed it when I need it and I know exactly how much to feed it for my uses, so I ever end up with too much. Sometimes I feed her more than others to be able make more loaves at once or use starter to make something else, like flatbreads or pancakes, but I only ever keep that 100g or so. Which is also what my guide for reviving my dried starter is based on, so that you always end up back at the same amount after feeding and using.
In between uses…
If you’re not going to use it for several weeks, keep it safely stored in the fridge with a firmly fitted lid. It will be perfectly fine and you do not need to take any special action. Many established starters have lived unused in fridges for weeks and months and have been absolutely fine, working perfectly when next used.
Change of plan…
If you got your starter out of the fridge thinking you were going to have time to make some dough up but it turns out you haven’t, just put it untouched back in the fridge. Unless it been a 7-10 days since you used it and it needs feeding, then do as above.
When you want to bake a loaf…
Take your starter from the fridge and let it come up to room temperature. Feed it with 30g of strong white flour + 30g of water, stir it well, and allow it to become fully active and ready to use, this can take 2-6 hours depending on the room temperature. If you feel that the mix feels a bit thin, add a tablespoon more of flour.
