Hello,
I am wondering whether it is possible to obtain yummy tempeh with a fermentation that would involve both R.oligosporus & A.oryzae. The rational being the inhibiting properties of A.oryzae on the growth of unwanted or even harmful fungal & bacterial strains. Moreover it sounds like good fun.
A study* suggests that A.oryzae will be helpful as long as it does not dominate R.oligosporus.
Now when it comes to taste & textures aka. yumminess, has anyone tried?
