Given the background description of some cooking related query, summarize the question into a title

[EX Q]: Recently my cousin started to make yogurt. She told me that she puts diced, fresh fruit (strawberries, peaches) into the inoculated milk (pasteurized or sterilized, I don't know. 1) and then let this set in the oven at ~50C for some hours. After this, she puts the yogurt into the fridge. She makes enough yogurt for ten days; on the tenth day she takes the last yogurt portion and makes some new. At the first thought I couldn't imagine that fresh fruits stay safe for ten days (I wouldn't eat cut fruits that stayed for ten days in the fridge!). But after some pondering I wondered if it's safe after all because the milk and the fruits are going to be cultured and undesired bacteria are going to be eliminated. I think freshly diced fruit only contain bacteria on the surface. 1 I saw a really big jug of milk. She lives in Georgia, US. I don't know what's the common treatment of milk there.
[EX A]: Soon-to-be cultured milk with fresh fruit safe for consumption?

[EX Q]: I sometimes find myself wanting to eat whole nuts in situations where I have no access to a nutcracker, whether because I'm at work or traveling or otherwise not in a place where I might be expected to keep a nutcracker on hand. I've had good luck squeezing two pecans together in my hand, but what other nuts are good for improvised cracking methods?
[EX A]: Which nuts can be cracked without tools?

[EX Q]: I have moved into a house with a nice Wolf-range griddle, and I would like to know what the primary advantages of the griddle are over a cast-iron skillet, including, is there anything I can do with a griddle that can not be done with a skillet?I have found that the primary downside to using the griddle is the time it takes to heat up, so when cooking for one, I would choose the skillet. The primary advantage of the griddle is that it provides a larger, easier cooking space. Am I missing other major advantages of having a griddle?
[EX A]:
What are the advantages and disadvantages to using a griddle instead of a cast-iron skillet?
