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

Input: Consider Input: Soaking liver in milk is said to be a common technique that supposedly helps to remove impurities, softens flavour, and tenderises the liver. I tried it, and the liver turned out alright, but it got me wondering: how does this work? What's the chemistry behind it? Exactly what's happening between the milk and the liver? Is it the acid in the milk tenderising the liver? That would mean I could soak liver in a marinade based on lemon juice or vinegar? (It doesn't seem like a terrific idea) Or is there something else involved? I searched around, but nothing I found seemed terribly exact.

Output: How does soaking liver in milk work?


Input: Consider Input: I was gifted with a soft serve ice cream dispenser. however it's such a pain to always keep the machine on and running each time I want ice cream--more so that it highly consumes electricity. I wish to know if there is a way I can produce my soft serve in a large quantity and store it in my freezer so I can always remove and take a scoop each time I want soft serve. I tried it once but it went hard as a rock and lost its texture when I allowed it to defreeze.Is there a trick to keeping it soft and close to the consistency in the freezer?

Output: Can I store soft serve ice cream in my regular freezer?


Input: Consider Input: I was just putting away my cornstarch when I saw this on the label: To make cake flour: For 1 cup cake flour combine 3/4 cup plus 2 Tbsp. all-purpose flour with 2 Tbsp. Argo Corn Starch.Of course I see this two days after paying a ridiculous amount of money for Softasilk.I usually use AP flour for simple cakes, but I'm making some really fussy desserts for the holidays. Some of those recipes call for cake flour and I've always gone ahead and bought cake flour for that kind of thing. Would I really get as good a result with that substitution?


Output: Is cornstarch and AP flour really a good substiture for cake flour?
