People are still making it today, even with the existence of baker's yeast.</p><p>The fermentation required to prepare it improves the flavor of the dough, and makes it easier for the body to absorb the <a href='nutrition.html#zinc'>dietary minerals</a> present in the grains.</p><p>Making sourdough bread begins with a sourdough starter. The starter is a fermenting mixture of flour and water containing microorganisms which include wild yeast and lactobacilli. The yeast produces carbon dioxide which leavens the dough, and the lactobacilli produce lactic acid which contribute flavor. The process is simple, it requires more waiting than active cooking time. We've made a summary of common questions and concerns when it comes to making a starter.</p><p><b><a id='discard'>WHY DISCARD?</a></b></p><p>Discarding starter is necessary as it quickly builds up in a jar and becomes difficult to manage. The discard works well in a variety of baked goods.</p><p><b>ADAPTING YEAST RECIPES</b></p><p>There are some key aspects to converting yeast recipes to sourdough, like hydration level and yeast. <a href='https://www.culturesforhealth.com/learn/sourdough/hydration-sourdough-starter/' target='_blank'>Hydration level</a> is the ratio of water to flour in a starter. You can maintain or adjust the hydration level with each feeding based on the ratio of water to flour you feed your starter. Aiming for 100% hydration, or equal weights of flour and water, is recommended.</p><p>To calculate how much added yeast is necessary, first you have to know that the rising power of 7 g of yeast (1 packet) is roughly equivalent to 226 g (1 cup) of sourdough starter.</p><p>With this information it's easy to approximate the amount of added water, flour and yeast in a recipe.</p><p><b>FEEDINGS</b></p><p>The starter needs feedings at <b>12 h intervals daily</b> in the first week, and <b>once a day afterwards</b>. As long as this starter culture is fed flour and water regularly it will remain active.</p><p><b>I forgot to feed my starter!</b> Forgetting to feed the starter isn't a big deal, feed it as soon as you remember. Feedings of longer than three days acidify the dough and may change the microbial ecosystem.<br /><b>Did i feed my starter too much?</b> Feeding the wrong amount won't kill it, but it may make it appear too dry or too wet and may not rise as expected. You can correct the feeding by adding either more flour or water, it will right itself.<br /><b>What's the liquid on top of my starter?</b> This liquid is the alcohol given off as the wild yeast ferments. This doesn't mean it's going bad, it indicates that your starter is hungry.</p><p><b>FLOUR</b></p><p>Using wholemeal instead of processed flour for your starter is a good idea because it provides a variety of organisms and minerals.</p><p><b>FILTERED WATER</b></p><p>Using filtered (carbon filter) or distilled water instead of plain tap ensures good fermentation, as sourdough relies on microorganisms that chlorine inhibits. Leaving tap water uncovered for 24 h will allow the chlorine to dissipate.</p><p><b>Can my starter go bad?</b> Starters require more attention on the initial 6-10 days it takes to create a healthy mature starter. It hasn't yet developed defenses that characterize a mature starter. Mature starter cultures are stable because of their pH level and the presence of antibacterial agents, this helps prevent colonization by unwanted yeasts and bacteria. Sourdough breads keep fresh longer than regular bread for this reason too. The ideal temperature for starters is 21 °C, but a bit higher and lower won't hurt it. Yeast dies at 60 °C. If you see an pink or orange streak on your starter, this is a sure sign it's gone bad, discard and start over.</p><p>Good luck with your starter, and be sure to give it a name! Ours is called Teki, after a tern in Miyazaki's Future Boy Conan.</p></div><dl class='ingredients'><h3>starter</h3><dt><a href='whole_wheat_flour.html'><img src='../media/ingredients/whole_wheat_flour.png'/><b>whole wheat flour</b></a><u>28 g</u></dt><dt><a href='water.html'><img src='../media/ingredients/water.png'/><b>water</b></a><u>60 ml</u></dt></dl><ul class='instructions'><li>Day 1.

Only discard before you feed it, not after. Why discard? Read the <a href='#discard'>notes</a> in the description above.

It's now possible to start using the starter to make sourdough recipes.</li></ul></main><footer><a href='about.html'>Grimgrains</a> © 2014—2022 <a href='https://creativecommons.org/licenses/by-nc-sa/4.0/' target='_blank'> BY-NC-SA-4.0</a><br><a href='http://100r.co/' target='_blank'>Hundred Rabbits</a></footer></body></html>
