What is the secret to a good 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 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.

Compared to whole wheat flour, rye flour is said to be the most nutrient- and amylase-dense option for a sourdough starter.

It would be best if you discarded some portion of your starter each time you feed it unless you want to continue to let it grow. Eventually, you need to discard the used “food” (flour and water) that's been used to sustain your starter during the last fermentation period.

maybe 68-70ºF (20-21ºC). "Room Temperature" makes our starters sluggish and our baking even harder. Goldie elegantly warms your starter jar, bringing your starter up to the “Goldilocks Zone" of 75-82ºF / 24-28ºC - not too hot, not too cold.

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.

How often do you change or clean your sourdough starter container? Use the same jar daily and keep it as clean as possible. During a feeding, discard part of your starter per usual and then scrape down as much residual starter as possible, reincorporating it back into the mixture.

Fed sourdough starter refers to a starter that has been fed flour and water (preferably by weight). You should feed the starter equal or greater than its weight after discarding a portion. You should wait at least 2-4 hours or until the starter is at its peak before you use it in your baking.

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.

Can I use tap water for sourdough starter? ›

*If making sourdough is new for you, do not be discouraged if you starter takes longer to get active than mine – stick with it, it will happen! *Tap water is usually fine, if you are not sure, use boiled and cooled water, you can use it at room temperature or cool; do not use distilled water.

The best flour blend for creating a new sourdough starter is 50% whole-meal flour (whole wheat or whole rye) and 50% bread flour or all-purpose flour. I recommend a 50/50 mix of whole wheat flour and bread flour.

If your starter gets completely covered on top with bubbles but does not rise, it is healthy but may just be a wet mix. Try reducing the water in your next feeding and see if you have different results. Also, the type of flour you are using can impede the rise of your starter.

Premature discarding and overfeeding will weaken your starter and elongate the process. Don't discard and re-feed a weak starter before it shows increasing bubble activity or height from the previous feeding. If you don't see more bubbles or a faster rise each day, skip a feeding, and give it more time.

In short, to “activate” each, you simply add flour and water, stir, and wait — that's all there is to feeding a sourdough starter.

The longer you go in between feedings, the more acetic acid your starter will develop. This acid creates a more sour flavor.

because it reacts with the acid from the sourdough starter to create carbon dioxide gas, which provides leavening. You don't want to add baking soda to the starter you are maintaining, because baking soda will raise the pH. The yeast will not grow unless the pH is around 3.5.

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).
