Given a paragraph about cooking, and a set of conversational question answers about the paragraph, answer a follow-up question from the paragraph. The paragraph has a prefix 'CONTEXT:'. Each conversation question has a prefix 'Q:' followed by answer prefix 'A:'. The final followup question has a prefix 'FOLLOWUP_Q:'.

[EX Q]: CONTEXT: If it's a small spot you can rub half a lemon on it till it's gone. If the entire inside has darkened you can fill it with water, add several tablespoons of cream of tartar (2 per quart) and boil it for 10 minutes.You can also buy aluminum cleaner, but the do it yourself is typically cheaper.In case you're wondering why I'm suggesting an acid for cleaning. It's actually alkali foods that stained your pot, not acidic. e.g. boiling potatoes. Acid actually cleans the spots put there by alkali foods. The common warning against cooking acidic foods in an aluminum pot is to prevent excessive amounts of aluminum being leeched into your food. <sep> Q: How to clean my unanodized aluminium pot? A: You can also buy aluminum cleaner Q: Does acidic food cause problems with an unanodized aluminium pot? A: It's actually alkali foods that stained your pot, not acidic Q: How else can I clean it? A: If it's a small spot you can rub half a lemon on it till it's gone Q: Do you have any other advice for cleaning? A: If the entire inside has darkened you can fill it with water, add several tablespoons of cream of tartar (2 per quart) and boil it for 10 minutes <sep> FOLLOWUP_Q: Thanks, any mor etips?
[EX A]: You can also buy aluminum cleaner, but the do it yourself is typically cheaper

[EX Q]: CONTEXT: First, remove some, but not all, of the end. Make sure to leave a little of the root intact, as this will make the next steps easier. Peel the onion and discard the peel.Stand your onion on one of the now-flat ends. Chop in half with your chef's knife.Lay a single half on the flat end. Working from root to cut end, make several cuts at dice width that cut almost to the root end, but leave a little bit still attached.Working perpendicular to your last set of cuts, make another set of cuts at dice width. This will leave you with cut pieces. When you get to the portion with the root, discard it.Repeat for your other onion half.During cooking, the layers should flake apart leaving dice sized pieces. <sep> Q: A definitive method of dicing an onion A: Lay a single half on the flat end. Working from root to cut end, make several cuts at dice width that cut almost to the root end, but leave a little bit still attached <sep> FOLLOWUP_Q: Any unusual and clever methods you know of?
[EX A]: Working perpendicular to your last set of cuts, make another set of cuts at dice width. This will leave you with cut pieces. When you get to the portion with the root, discard it

[EX Q]: CONTEXT: No, the fat will not render at about 50 C (122 F).However, you said core temperature, which implies the surface temperature will be higher assuming you are not cooking in a 50 C oven (which you should not, for safety reasons). If you are pre-cooking the steak at, for example 120 C (250 F), the surface will be hotter by the time the center reaches your target temperature, so you may get some rendering.Still, there is a quite simple answer: trim the excess fat. What remains should char and develop a good flavor when you sear it on the grill. <sep> Q: will the fats render when the steak is being slow cooked at low temperatures? A: the fat will not render at about 50 C (122 F Q: When will fat render ? A: at, for example 120 C (250 F), the surface will be hotter by the time the center reaches your target temperature, so you may get some rendering <sep> FOLLOWUP_Q: is there any other way to render the fat without going to such high temperature ?
[EX A]:
trim the excess fat. What remains should char and develop a good flavor when you sear it on the grill
