yeast / cinnamon test

I had never heard that cinnamon kills the yeast as Coz had been told.Therefore it seemed a test was in order.I added one tsp yeast into each of 2 bowls, one also got an addition of 1/2 tsp cinnamon.Added 1/4 cup warm water,after several minutes added 1/4 tsp sugar to each,should have done to start with.After 5 min not much.30 minutes alot going on in Both bowls.So it seems cinnamon does not kill yeast activity. OOpps still didn't change time stamp..



 1 tsp instant yeast



1 tsp yeast in both

1/2 tsp cinnamon with yeast

added 1/4 tsp sugar
