Question Do I have to use a new packet of Bulgarian Yogurt Culture every time I make a new batch of yogurt?
Jerri’s answer Not necessarily. When you make a new batch, instead of using more powdered yogurt culture, you can use a few tablespoons of yogurt from your previous batch. This reculturing method works for yogurt made with any of our yogurt culture starters.
When your new batch of yogurt is ready to eat, set some aside to use as a starter culture later. All you have to do is fill up an ice cube tray (or two) with some of your yogurt, and freeze it. Then, the next time you want to make yogurt, simply add four or five cubes to your warmed milk, allow them to dissolve completely, and incubate in your yogurt maker as usual.
Theoretically, our yogurt can be recultured in this manner indefinitely. Note that some of our customers have reported that the yogurt starts to get tart if you reculture it more than ten times. However, others who use this method routinely claim there’s no change in the flavor. Try it yourself and see what you think!
