After a day of incubation, one of our fellow microbiology classmates took the two cups and put it in the refrigerator.
Then when we returned to the lab the following day we tasted and looked at the two yogurt cups. We found that heating the milk and yogurt not only tasted better but the consistency was a lot better than the not heated cup. The cup that we did not heat looked more liquidly than the other one and tasted really sour.
Here are some pictures of Rose tasting the yogurt and what the yogurt looked like!
