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

Input: Consider Input: Many recipes call for first bringing milk up to boil.I normally boil 1 quart (1 litre) of milk in a 3-quart stainless steel heavy bottomed pan:use low heatkeep scraping the bottom of the pan every 1-2 minute Milk comes to a boil in about 40-45 minutesIn spite of my carefully watching the milk, at the end, when I pour of the milk, I see a "crust" form on the pan. This makes cleaning up a pain.Further, it is hard to constantly watch and scrape the milk every 1-2 minutes.Is there a more convenient way to bring milk up to a boil?Looking for:Unattended, fool-proof methodEasy clean-up at the end.Yes, I am aware of this other question:Quickest, and safest way, to bring milk to boil?However, my question is a bit different.

Output: Can I boil milk unattended (and still keep the pan clean)?


Input: Consider Input: What are the mechanics of water boiling over? How can you stop it from happening? Is it more likely to happen with certain ingredients? Which? How does the amount of water effect the likelihood of water boiling over? What role does burner temperature have? Will it only occur during a rolling boil?This is brought up by this comment by MeltedPez in one of the cooking pasta questions: The only other argument for using more water is that less water is more likely to cause the pot to boil over. Basically the starch in the pasta makes it easier for the water to form bubbles that collect and spill over when not paying attention. I've found that with a very low pasta to water ratio can end in a messy kitchen. This seems very counter intuitive to me initially, as I feel less water should make it harder to boil over the edges.

Output: What causes water to boil over?


Input: Consider Input: I use oil for cooking in the Teflon coated pan. I put the pan on a very low fire. (Simmer) Lately I have found that the onions get stuck to the bottom of the pan.How to know whether the teflon coated pan's life has reached end? Does it change colour or something else?


Output: How to know whether the teflon coated pan's life has reached end?
