TASK DEFINITION: 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:`.
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 

SOLUTION: Do tomatoes have to be skinned?

PROBLEM: CONTEXT: If you have a gas stove, you need a hood to send the exhaust outside. One that recirculates is not sufficient.In my experience, the recirculator hoods work OK if you're not doing a lot of cooking. If you do, however, you'll end up with a nasty, greasy dusty coating on everything in your kitchen. I wouldn't bother with a recirculation hood if you ever cook things that involve grease or smoke. For someone who mostly heats up processed foods, it's probably good enough.  <sep>  Q: Are recirculation extractor hoods good? A: In my experience, the recirculator hoods work OK if you're not doing a lot of cooking  Q: How good are they? A: I wouldn't bother with a recirculation hood if you ever cook things that involve grease or smoke  Q: What kind of hood do you recommend? A: If you have a gas stove, you need a hood to send the exhaust outside. One that recirculates is not sufficient 

SOLUTION: Will a pipe for the exhaust be needed?

PROBLEM: CONTEXT: The key difference from my perspective is cleaning. Silicone is the easiest material in my kitchen to scrub clean, with the possible exception of stainless steel. Cloth is very far down the list.Also, depending on the texture of the cloth, more food will almost certainly stick to the cloth, unless it's sealed with something, in which case what is it sealed with? And how is it sealing the fiberglass in?I use the kind with a thin grid of fibers inside the silicone. It adds more stability and lets the overall thickness be thinner for better heat transmission, compared to a plain silicone silpat. As long as I don't use it as a cutting board, the fiberglass stays safely inside. It does add a very slight grid texture to the bottom of loaves, but it's barely noticeable and doesn't look bad at all.The pyramid kind, which would reduce food contact and increase drainage and airflow, sounds like it would be good for specific applications, but not something I'd make a batch of cookies on.  <sep>  Q: What are some differences between cloth, fiberglass and silicone baking mats? A: The key difference from my perspective is cleaning. Silicone is the easiest material in my kitchen to scrub clean, with the possible exception of stainless steel. Cloth is very far down the list 

SOLUTION:
What are some characteristics of the fiberglass baking mat?
