I think that one of the hardest things to master with natural yeast baking is knowing the best time to use your starter for maximum results. For beginners, I always suggest a set regimen of the 3-4 day period following a feeding (at least 24 hours after a feeding), but if you pay attention to your starter activity, you can learn to take your cues from the starter itself.
Starter that is “happy” (as I like to call a healthy starter) is very active, and very bubbly. After a feeding, the starter will bubble up happily, doubling it’s volume, and then recede as it consumes its food source.
The best time to use your starter for baking bread is the day or two it first begins to recede in the jar.
There are two ways to tell when your starter is “receding.”
- You will notice that the top portion of your starter has fewer bubbles than the rest of the starter. That is because the starter is beginning to collapse on itself.
This starter was so happy it rose all the way to the top of my jar. Can you see how there are more, bigger bubbles in the lower half of the starter than the top?
- You will notice small streaks along the glass where the starter has slid down as it recedes.
Again, this starter was full almost to overflowing after I fed it. Can you see the small streaks along the glass where it has collapsed some?
Let’s look at why this is the best time for baking.
Starter organisms have metabolisms just like we do, only much slower because they live in the fridge. (they can go for days between meals)
With our own metabolisms, the best way to stay happy and well-balanced in our diet is to eat the right foods at the right time. Periods of extended lack of food, or excessive bingeing make us unstable and very cranky. But, if we allow our bodies to consume what we have eaten, then provide more of the right foods BEFORE our blood sugar dips, our bodies will function at optimal capacity.
The same goes for starters. A starters metabolism is at its peak just after it has digested its food and before it gets overly hungry and cranky (sour). When you use your starter in baking at this point. You will get optimal flavor and optimal height from your bread. In a bread dough, your starter will start gobbling up all the new “food” (it is hungry, after all) and producing big happy bubbles in your dough.
Here are two reasons naturally leavened bread will sometimes fail to rise:
- Your starter has gone too long between feedings, and too many of your yeasts have died. (look in the trouble-shooting section for ways to remedy this) There are simply not enough of them to produce good bubbles in your dough. This bread will turn out dense and often sour from the imbalance of yeasts to lactobacilli.
- You are using your starter too soon after it has been fed. If your starter organisms haven’t had time to reproduce and consume all the food in the container, you may not be getting as much actual starter in what you measure out as you think. For example you might measure out 1/2 cup for a recipe, not realizing that only 1/4 cup of that amount actually has starter organisms in it and the rest is just uneaten “food” (wheat and water).
So keep an eye on your starter (I keep mine in the fridge door where I can see it every day), watch for the signs, and you will be very glad you did!![]()
This is one day after the earlier pictures were taken. See how far it has fallen? I can still use this starter well in a recipe and get fluffy, great tasting loaves. Once it has started developing liquid on top (probably tomorrow or the next day) there is the possibility my loaves will be slightly heavier and stronger flavored.
