Each conversation question has a prefix `Q:` followed by the answer prefix `A:`, and the follow-up question has a prefix `FOLLOWUP_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  <sep> FOLLOWUP_Q: Does acidic food cause problems with an unanodized aluminium pot?
Yes

CONTEXT: This really depends on the locale. For example in Seattle we have a couple of Washington State grain farms and mills that do sell their product at farmer's markets. If you have trouble tracking down a miller directly, you might do well to ask at your local natural foods co-op if they can source this or direct you to people who can help. Another place to ask would be at your best local artisanal bakeries, as they may well be using local flours.  <sep>  Q: I was wondering Where can I get local grains in bulk? A: This really depends on the locale  <sep> FOLLOWUP_Q: Is there a good source to buy them online?
No

CONTEXT: The recipe calls for ground almonds. This can be done in a food processor. You may wish to remove the almonds' skins beforehand, and you also may wish to toast them. Both of those are very common, even though neither is essential. With this particular recipe, I'd be inclined to toast them but leave the skins on. Once you've made those decisions, measure out the sugar called for in the recipe. Set it aside. Then place the almonds in the processor and add two or three heaping tablespoons of the measured sugar. Pulse until you reach a grind that resembles a meal, or very course flour. The finer you grind the almonds, the more carefully you must watch them. Eventually, the almonds will begin to turn to a paste. The sugar is helping to prevent it, and that's helping you to get a finer grind. However, overprocess and the almonds will turn to paste. If you're carefully watching for it, though, you'll see it begin to happen before it goes too far.  <sep>  Q: How do I grind almonds for making marzipan? A: This can be done in a food processor  <sep> FOLLOWUP_Q: How fine should they be ground?

Yes
