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:`.

Q: CONTEXT: The ripening itself is caused by ethylene gas released by the food, which is trapped by any kind of bag.As far as I know, there's nothing inherently special about a brown paper bag, other than the fact that it's porous and thus still allows some air to get in and out. Plastic ziplock bags have no ventilation, so they don't work nearly as well.  <sep>  Q: Why does a brown paper bag speed ripening? A: As far as I know, there's nothing inherently special about a brown paper bag, other than the fact that it's porous 

A: So many people suggest using them for bananas. Is there something special about the banana?

Q: CONTEXT: Dust all three inclusions (the chips and nuts) and then place half of the plain batter (that has no inclusions added) in the pan(s), add the inclusions to the remaining batter and mix lightly. Pour that batter evenly over the batter already in the pan(s) and bake. Don't cut the pistachios in more than half or they will be too small.  <sep>  Q: How to add pistachios in a white chocolate mudcake A: Dust all three inclusions (the chips and nuts) and then place half of the plain batter (that has no inclusions added) in the pan(s 

A: Should I dust them with flour?

Q: CONTEXT: To clarify: forced-air (a/k/a "convection", a/k/a "fan bake") ovens rely on a fan to circulate the air in the oven. The fast-moving air substantially enhances the rate at which heat is transferred to the food. It is particularly good where you want the surface to brown, such as roasts and breads; it is not as good for more delicate items, such as custards and cakes, which can set too quickly or get dried out. For cookies, it depends on what effect you want, but many standard types do well in forced-air ovens because the fan helps ensure that the whole oven stays at a uniform temperature despite the presence of several trays. (Of course, the tray closest to the heating element will still cook faster than the one farthest away, so you will still have to swap them partway through.)The general rule for using the fan is to set the oven temperature 25 degrees F (15 C) lower than what the recipe calls for using in a regular oven. Even then, don't go strictly by cooking time, as ovens vary; rather, be sure to check on your food regularly to see how fast it is cooking. You may need to cover your food to prevent over-browning, or perhaps adjust the oven temperature.  <sep>  Q: When to use convection/fan bake vs bake###Are there any general rules to follow when choosing between bake and fan bake to cook something in the oven? A: The general rule for using the fan is to set the oven temperature 25 degrees F (15 C) lower than what the recipe calls for using in a regular oven  Q: What effect does each have and what are the advantages and disadvantages of both? A: forced-air (a/k/a "convection", a/k/a "fan bake") ovens rely on a fan to circulate the air in the oven. The fast-moving air substantially enhances the rate at which heat is transferred to the food 

A:
I see. Anything else I need to know
