sourdough starter not working
I made a sourdough starter using equal parts of unbleached whole wheat flour and water and switched to unbleached AP flour on fifth day. The starter was very active. After seven days I froze some starter. I never did a float test as The recipe I followed for starter didn’t say it and I had never read it until now on this website. I made the leaving using different feeding based on recipes I was going to follow (25 g starter, 25 g wheat flour, 100g AP flour, 100g water). The leavain rise to 2.5 times but every time I made bread or pizza, it was disaster as final dough too loose. After wasting so much effort, time and dough three times I got so frustrated and decided to trouble shoot. My finding that my leavain doesn’t float. Then I decided to thaw the starter and it is completely inactive. Help......please
Shall I start new starter? If yes, can I start Sarah Owens recipe of 60g each flour and water with whole wheat flour and when to switch to AP flour?
