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:`.
question:
CONTEXT: We have a convection oven and almost always use it. I can't remember the last time we didn't use convection. Our model automatically decreases the temperature, so if you set it for 300, then it will heat to 275. Not sure if that is a magic 25 degree number, but it seems to work. Almost all recipes cook time wise as they would with a non-convection oven. Our also has a single and multi-rack mode, and it circulates the air differently in that case. We have NEVER had any problems with the food drying out more with the air circulation as they say that is a common negative.I am sure the effectiveness varies oven to oven, but in our case, we always use it (except for broiling of course).  <sep>  Q: When should I use convection when baking? A: in our case, we always use it (except for broiling of course 
answer:
When is it better to broil?


question:
CONTEXT: A number of Chinese restaurants are happy to prepare it without pork or beef. I've seen it with pork (most common) or beef (sometimes).A vegetarian Chinese place that I occasionally visit uses a "vegetarian ham" along with some vegetables like peas to augment the custardy texture of the soft tofu. I like to add some ja tsai (zasai, depending on romanization preferences) pickles in there, though I'd guess that's not that common.Pork is not absolutely essential to the identity of the dish, but it's certainly the most likely version to be served.  <sep>  Q: can i make Ma Po Doufu without Pork A: A vegetarian Chinese place that I occasionally visit uses a "vegetarian ham" along with some vegetables like peas to augment the custardy texture of the soft tofu  Q: Would the dish work with chicken/beef? A: I've seen it with pork (most common) or beef (sometimes  Q: can i make this wihout any type of meat? A: some vegetables like peas 
answer:
do i have to make this with tofu?


question:
CONTEXT: The sugar is mostly just for flavor. I use sugar when making pickled beets and eggs, but don't use it in my dill pickles or pickled peppers and onions. It just depends on if you are trying for a sour, sweet and sour, or sweet pickle (note that there is no vinegar in many fruit pickles).Before you decide to run off and leave out the vinegar, however, I would note that for pickling safety purposes there has to be enough acid to keep botulism causing bacteria from forming and peppers are a low acid vegetable. If you wanted to eliminate the vinegar, you'd have to move to pressure canning.  <sep>  Q: What's the purpose of sugar in a pickling solution? A: The sugar is mostly just for flavor 
answer:

Does is affect the preservative qualities?
