While the program does default to pasteurizing in the 24th hour, the mobile app has an optional alarm when the incubation stage is complete. At which point you can remove the raw tempeh or shut off the Protein Pod altogether.
The current list price for a single Starter Culture Cup is $2 and packs of 6 for $10.
The Protein Pod does not require that you use our brand of culture or legumes. You may choose to use the brand(s) of your choice although prep time and quality will vary.
