30	Note: ‘Normal rate’ is the quoted usage rate from the manufacturer. Full strength powdered starters (Akita Konno, Higuchi) are typically used at a rate of 70g per 200kg rice, while granular starters are typically used at 200g per 200kg rice. For different manufacturer’s rates, change the quantities in bold on the top row. You can also use these entries to make a custom rate, for example to match a dispersed starter amount.
