Sourdough Starter Recipe (Natural Fermentation) (2024)

FAQs

How do you make enough sourdough starter? ›

There is no single best ratio, but I've found a ratio of 1:5:5 fed twice daily at 12-hour intervals to produce a sourdough starter that's strong and healthy. This ratio corresponds to 20% ripe starter carryover, 100% water, and 100% flour (a mix of whole grain rye and white flour) at each feeding.

A 100% hydration sourdough starter is a culture which is kept and fed with water and flour at equal weights. Like for instance 5 oz water to 5 oz flour. A 166% hydration starter is fed with equal volume of flour and water, which most typically is one cup of water (8.3 oz) and one cup of flour (5 oz).

A 1:2:2 feeding ratio would consist of one part existing starter, two parts flour and two parts water. For example, if you have 30g of existing starter, you would feed it 60g of flour and 60g of flour. The most common feeding ratios for daily maintenance are 1:1:1 or 1:2:2.

You should see the formation of lines of gluten strands and/or webs of gluten that have formed. The texture and feel should no longer be sticky but only tacky. If the dough is sticking to your finger or hands rather than sticking to itself, it is not done fermenting.

A dark watery layer, called 'hooch' (see this video) will appear on its surface, but that's absolutely normal – it doesn't mean your starter has died. This is just a sign that your starter has over fermented. Just remove the hooch before you feed your starter again.

Sourdough starters should be fed a minimum ratio of 1:1:1, meaning equal WEIGHTS of starter to flour to water. If you feed your starter this way and keep it at a consistently warm temperature 78ºF, your starter should peak and become active/bubbly in about 3-4 hours.

Overfeeding can be a cause of this “sickness,” as can lack of feeding and neglect. Because, yes, you can overfeed your sourdough. The explanation is quite simple: if you add too much water and flour, you're basically diluting the natural population of yeast and bacteria.

If you have too much starter compared to the additional flour and water you're adding, your hungry starter consumes all the nutrients and then it's not as bubbly.

To keep a smaller starter, you will save just 20 grams (about 1 heaping tablespoon) of active starter, feeding it with 20 grams of water and 20 grams of flour. This will yield 60 grams of starter which is just enough to maintain.

If you don't get rid of the excess, eventually you'll have more starter than your feedings can sustain. After a few days, your daily 1/4 cup flour and water won't be enough to sustain your entire jar of starter, and your starter will be slow and sluggish, not much better than discard itself.

Am I underfeeding my sourdough starter? ›

Your starter may have a little bit of a smell if it hasn't been fed in a while, and your cooking projects will taste a little more sour to reflect that. So if you want to avoid the super sour sourdough taste, you might just need to feed it more often and not let it sit out on the counter as long.

Just a note here - it is normal for a sourdough starter to be stiffer when you first feed it and then thin out a little as it ferments. It should however be mousse like and aerated when it peaks.

All-purpose Flour

It strikes a perfect balance of softness and structure, making it an ideal choice for various recipes. Due to its wide availability and affordability, all-purpose flour is often my top recommendation for creating and maintaining a sourdough starter.

Have you ever wondered whether you have to clean your sourdough starter jar? The simple answer is you don't need to clean your sourdough jar. It's just not necessary to clean your jar all that regularly, unless it's super crusty or you can't get your starter out or fresh flour and water in.

Typically, bulk fermentation will take between 6 to 8 hours, but could be longer or shorter by manipulating starter amount and temperature. Ideally, you don't want to allow sourdough bread to cold ferment for longer than 72 hours.

However, the longer the dough ferments (and especially at warm temperatures), the lactic acid bacteria stimulates something called the “protease enzyme.” The protease enzyme eats gluten and starts to deteriorate your loaf.

Over-fermented sourdough starter can get a layer of “hooch” on top (Google it), which has a small amount of alcohol in it. But when you BAKE the bread the alcohol will burn off much the way it does when you add wine, beer, sherry or brandy to recipes. So I would say don't worry about it.

Overproofed sourdough is preventable but also salvageable. Reshape the dough, bake it as a pizza or flatbread dough, or bake it and turn it into breadcrumbs for granola.
