My yogurt didnt thicken in the allotted time period?
A. Occasionally yogurt may take longer to thicken than specified in the instructions. This can happen for several reasons including possible drafts which might result in a lower temperature where the yogurt is culturing. It is very important that proper temperature is maintained. It is acceptable to let the yogurt culture for longer than indicated by the instructions and even if the temperature was a bit too cool, this will likely resolve the issue. Simply check the yogurt every two hours or so and place it in the fridge once the culturing process is complete.
