Given a paragraph about cooking, and a set of conversational question answers about the paragraph, generate a relevant question to the topic of the paragraph. The paragraph has the prefix 'CONTEXT:'. Each conversation question has a prefix 'Q:' followed by the answer prefix 'A:'.

[Q]: CONTEXT: Fat doesn't spoil like other foods. No bacteria can live in fat. Going rancid is a chemical reaction in which the fat molecules break down. So "leaving out" is not a problem. The major factors in going rancid are light and air. The more light hits your fat, the sooner it goes rancid. Also, rancidity occurs when the fat is oxidized, meaning that if you prevent contact with air, your fat will last longer. Both factors are minimized by transferring the fat to a tightly closed opaque container. With liquid oils, you use a dark colored bottle. As bottles are impractical for solid fat, just strain your grease into a jar, close it, and put it in a cupboard. The shelf life should be many months, probably more than a year. Also, don't worry that you can get something nasty when the grease goes bad unnoticed. Rancid fat isn't a big safety risk, and ingesting it in small amounts is not problematic. If it stinks, throw it out. Before that, there is no problem eating it. The above assumes pure, well-strained fat. Pieces of fried meat left over in the fat are a safety risk, even tiny ones. <sep> Q: How long does grease take to go bad/rancid when sitting out? A: The shelf life should be many months, probably more than a year Q: is that true for all types of grease? for example is it different for bacon grease versus ground beef grease? A: The above assumes pure, well-strained fat. Pieces of fried meat left over in the fat are a safety risk, even tiny ones
[A]: So, it is the meat particles in the fat that can make it go rancid not the actual fat itself, should I sieve it before storing it?

[Q]: CONTEXT: You don't need to defrost it, you can add cold roux directly to a boiling liquid. To avoid lumps from the roux, most cooks suggest you either add cold roux to a hot sauce, or cold liquid to hot roux. If you heat the roux gradually with the liquid you may get lumps, and don't get a good impression of how much thickening is going on until it heats fully. <sep> Q: What is the right way to defrost roux? A: You don't need to defrost it, you can add cold roux directly to a boiling liquid Q: The way i've been using them till now is to take the require amount of milk in a pan, add the cubes and then let it be for 5 minutes or so THEN start the heating. A: To avoid lumps from the roux, most cooks suggest you either add cold roux to a hot sauce, or cold liquid to hot roux
[A]: What should I do if it's still lumpy?

[Q]: CONTEXT: I'm specifically answering your question "Is it okay to use a microwave in convection mode without the turntable?" -- Yes.Your own answer points out the reality that if a pan is too large then the turn table will simply hit the sides of the microwave oven and then stop turning. There is nothing wrong with this. There is nothing wrong or damaging to have a metal tin touch the metal sides of your oven.How was your baked items bottom? If you can sit your tin up so there is air flow under your tin, then you will improve the baking efficiency and it will bake more evenly.CAUTION: If anyone else is reading this question and wondering about their own machine, then you really need to take caution about the "convention only" mode. You have to make sure there are NO microwaves in this mode or else your metal will conduct and you could have a serious explosion or break your microwave oven. <sep> Q: Is it okay to use a microwave in convection mode without the turntable? A: There is nothing wrong or damaging to have a metal tin touch the metal sides of your oven
[A]:
What is a damaging situation for my microwave ?
