PROBLEM: 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?

SOLUTION: Yes

PROBLEM: CONTEXT: Red lentils have no skin and are thus more absorbent. They literally sucked up the wee bit of water clinging to them along with their neighbors. Surface tension of the water couldn't be broken by the light-weight pulses. When crumbled apart, the brick doesn't feel pasty, no? Next time maybe pour lentils into water; either way, no harm to finished dish. <sep> Q: What made these red lentils 'brick' together? A: Red lentils have no skin and are thus more absorbent <sep> FOLLOWUP_Q: Do you have any other information on red lentils?

SOLUTION: Yes

PROBLEM: CONTEXT: One of the first things I learned in Indian cooking is that the combination of tomatoes, onions and ginger is self-thickening. As time went by, I realised that the thickening effect is far more noticable with old varieties of tomatoes - "beef" tomatoes and a lot of the modern varieties are difficult to thicken unless partially fried first.Despite the absence of ginger, I suspect that the thickening is purely a natural action between the tomatoes and the onion, and that the tomatoes used were some particularly nice old variety. <sep> Q: Why did my tomato soup turn thick and brownish? A: One of the first things I learned in Indian cooking is that the combination of tomatoes, onions and ginger is self-thickening Q: The above combination with garlic, onions, spices can't be all wrong, can it? A: beef" tomatoes and a lot of the modern varieties are difficult to thicken unless partially fried first <sep> FOLLOWUP_Q: What went wrong with the color?

SOLUTION:
Yes
