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:'.

Q: CONTEXT: Basically, a good stock is fairly concentrated. In general, home cooks use too high a water to bones/veg ratio for a proper result. So, when you leave your stock uncovered you are concentrating everything and, perhaps, getting a good result...at least one you like. However, this is difficult to tell without knowing your recipe. With respect to adding water back later, it is not an uncommon practice to reduce a well-made stock further, by half or more, simply for storage purposes. Then when ready to use, water is added to bring it back to the original strength.  <sep>  Q: Should I reduce stock and then add water? A: it is not an uncommon practice to reduce a well-made stock further, by half or more, simply for storage purposes. Then when ready to use, water is added to bring it back to the original strength  Q: Does that effect the flavor? A: a good stock is fairly concentrated  <sep> FOLLOWUP_Q: Is there another way to make stock?

A: or

Q: CONTEXT: A pizza stone in a normal oven will only get the maximum temperature of the oven (probably not more than 280 ÂºC / 530 ÂºF).A specific pizza oven will gett hotter (the one you linked gets 390 ÂºC / 735 ÂºF and, indeed has a stone inside).If you want to get Italian style pizzas, go for the pizza oven. They need that high temperature in order to be ready in (ideally) 90 seconds. Those Ferrari ovens are one of Italian's favourite ones, albeit they'll need a bit more time than 1.5 minutes achievable in wood fired traditional pizza ovens. You (probably) won't be able to achieve those high temperatures with a normal home kitchen oven, unless you have a pyrolytic home oven, and hack it in order to cook in it during the pyrolysis cycle.As for the waiting time between pizzas using a stone, consider it as a capacitor (or a rechargeable battery): It takes heat (until is soaked up), and then gives it back. Once you make 1 pizza (or a loaf of bread), it needs to soak (a bit) again.  <sep>  Q: Differences between the oven stone and the pizza oven? A: A pizza stone in a normal oven will only get the maximum temperature of the oven  <sep> FOLLOWUP_Q: Which tastes better?

A: If you want to get Italian style pizzas, go for the pizza oven

Q: CONTEXT: Flour is a thickening agent, plain and simple. However adding it without cooking it first can lead to your dish having a raw flour taste, and you can get blobs of flour in it, so I would ignore the recipes which say coat with flour without cooking it first, or use cornstarch (cornflour) instead. Alternatively you can make a roux with flour in a separate pan and add it in later. This is simply mixing equal weights of flour and butter and cooking it in a frying pan until it has the color you want. A lighter roux will add a paler color and a milder flavor, a darker roux adds a deeper color and richer flavor.  <sep>  Q: Why should I roll the meat in flour for a ragout? A: I would ignore the recipes which say coat with flour without cooking it first  Q: What would you recommend? A: use cornstarch (cornflour) instead  <sep> FOLLOWUP_Q: Why would you say cornstarch instead of flour?
