Given the background description of some cooking related query, summarize the question into a title

Ex Input:
I was watching a video recipe about peanut butter cookies. The maker mentioned that you shouldn't use all natural peanut butter for making those cookies, because the oils would make your dough split. You should use the other kind (I have no idea what this is).Is this true?My peanut butter contains these ingredients: peanuts, vegetable oil, vegetable fat, salt. I'm assuming this isn't 100% natural peanut butter? Is it only natural peanut butter if it contains only peanuts?

Ex Output:
Is it true that natural peanut butter splits in cookies?

Ex Input:
I plan to make a sizable quantity of chicken stock this weekend. Since I can't actually eat that much chicken, I just bought several pounds of bones, figuring I'd save the effort and expense of cleaning and butchering entire chickens.But now I'm wondering: Can I roast the bones by themselves?Most resources seem to agree that stock made from roasted bones is richer than stock made from bones that were boiled raw. However, every "recipe" I've looked at assumes that whole chickens are being used. I've never been taught or seen instructions on how to roast just the bones.So I have a few questions related to roasting the bones:First, is it actually practical? Is there any reason I shouldn't consider this?What would be the recommended oven temperature and cooking time for about 5 pounds of bones?Assuming I use butter as the base, how much would I likely need?Does it make any sense to brine the bones, or to season them at all before roasting?Should I bother including vegetables or other flavours in the roast, knowing that it's just going into a stock afterward that will have its own separate flavours?My intuition is that any special preparation, seasoning or additives would be pointless, but I'd prefer to go by facts rather than intuition. And even if I'm correct I'd still like to get some rough guidelines as to the oven settings, because if I accidentally burn them then the whole endeavour is a bust.

Ex Output:
How can I roast chicken bones (without meat)?

Ex Input:
I like eating food with phyllo dough and I like preparing such food. However, phyllo dough is not easily available where I live. The only packages I can find are rather large. I usually use how much I need, then cover it as best as I can and store it air-tight in the freezer for later use. If I thaw and refreeze and rethaw some sheets, they tend to get dry.Even just working with non-frozen phyllo dough, can make your sheets dry out if you don't work quickly an/or with a wet towel.I was wondering if you could do anything to reverse this process. Is there a way to rehydrate phyllo sheets?

Ex Output:
Can you rehydrate phyllo dough?
