How to Make Sourdough Starter

Day 1: Mix

Day 2 and 3: Sit and Wait

Ways to keep sourdough starter warm:

FAQ : What if my starter rises and falls before twenty-four hour period 4 ? Can I move on to the next steps early?No , it ’s best to hold back . Sometimes , there is an initial volley of very vigorous activity on day 1 - 2 , but that is usually cause by a different type of bacteria that quickly grows then pass off .

Day 5: Rest and Wait

Nothing to do today ! Just let the new starterrest and rise . During this metre , the settlement of bacteria and barm will happily bung on the unfermented flour you supply , exponentially increasing their population as they do .

Day 6: Discard and Feed Again

Two days or about 48 minute after the first feeding , you should see a mickle of activity and bubbles in your starter now ! It also in all likelihood rose even higher than the first sentence . If so , it ’s time tofeed it again – just like you did on day 4 .

When you see hooch , you may either stream it off the top or simply unify it back in , and then throw away and feed as common .
