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

[Q]: I'm wondering if it matters whether you start from acid alone (lemon, vinegar or citric) vs something like acid + rennet. So the whey left over from making paneer, vs the whey left over from making mozzarella. Can you use either to extract the ricotta?
[A]: Does method of coagulation matter when extracting ricotta from whey?

[Q]: I have 5 - 6 lbs of sauerkraut in a crock with a water vacuum seal. I read that the first 24 - 48 hours are crucial to the success of the kraut. I also read that the kraut should develop its own liquid during this time, and that one can pour boiled water on top if it doesn't. However, I also read that it shouldn't be disturbed for a fairly long period of time. I am a bit confused. Should I check on the progress after a few days, or not?
[A]: How long should I wait before I lift the lid of my sauerkraut crock?

[Q]: Whenever I go to a BBQ and sausages are cooking, the chef will always prick the sausages while they are cooking. I have no idea what this does, I assume it's to get the fat out, however I recently read that you should never prick sausages as it results in them being dry inside?So my question is, should I prick sausages with a fork or knife during cooking?
[A]:
Should I prick sausages during cooking?
