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:`.

CONTEXT: Bleach is your best bet. Scrub it with a long-handled scrub brush and either liquid bleach or Ajax and water. Let it soak a bit before rinsing it out. Since it's stainless steel, the bleach won't do it any harm and will kill off any organics growing on it.In my experience, the pink stuff is a mold, not flouride.  <sep>  Q: What is a thorough way to clean my dish rack? A: Scrub it with a long-handled scrub brush and either liquid bleach or Ajax and water 
We've had it for about 6 months now and I'm noticing pink mold...will it remove the mold?

CONTEXT: To prevent the sticking, you might want to use a spray oil, maybe even just on the foil before you put the vegetables and potatoes on. It's a tiny amount of oil, not enough to make things noticeably greasy, but will be pretty effective. Another spray over the top will make them brown a little more nicely and may even prevent a little drying out. Alternatively, you can just toss them all in a bowl with a small amount of oil; it really doesn't take much, and I'd hardly describe it as "covering with a lot of oil."As for preventing things from drying out, first and foremost, don't overcook them. Broccoli and onions both roast very nicely, but you definitely want to pull it out before it starts browning/burning too much. If you slice the potatoes thinly enough, they'll cook in roughly the same amount of time as the broccoli and onions. So if things are getting overcooked, just don't leave them in the oven as long.You can also always try covering them. Another sheet of foil over the top will trap a fair amount of moisture, letting them steam a bit and probably preventing some burning as well.(I suppose it's also possible that it's all drying out because you're cooking them too slowly, so they have plenty of time for moisture to escape, but that seems less likely given the way you described things.)  <sep>  Q: Looking to bake side dishes, how do I stop problems with dryness A: As for preventing things from drying out, first and foremost, don't overcook them  Q: Is there any way to keep stuff from sticking to tin foil? A: you might want to use a spray oil, maybe even just on the foil before you put the vegetables and potatoes on  Q: I don't like too much oil, I may just have to boil my vegetables, have you ever heard of boiling onions? A: It's a tiny amount of oil, not enough to make things noticeably greasy, but will be pretty effective 
Is there anything else I could use?

CONTEXT: Can't comment on the nutritional side of things, but the main reason I can think of for not always including it is that it has a slightly different flavour. A much more intense lemon flavour is provided by the zest while the juice has the more tart elements (and of course water).If you're just interested in avoiding waste, you can freeze the zest.  <sep>  Q: Are there any reasons not to include the zest when citrus juice is an ingredient? A: the main reason I can think of for not always including it is that it has a slightly different flavour  Q: How does the zest change the flavor? A: A much more intense lemon flavour is provided by the zest 

Is it the same for all citrus fruits?
