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:`.

[EX Q]: CONTEXT: Our brains are wired to consider food more palatable if the dedicated taste receptors (one of the six basic tastes) for salt are triggered. And in a non-urban world, salt/sodium is a valuable nutrient; the fact we might have it too readily available in the developed world doesn't change that we would DIE on a zero-sodium diet (mind that animal products like meat aren't zero-sodium, and that herbivores tend to love licking salt where they find it!). So our brains have a good evolutionary reason to like salt.Also, salt actively interferes (negatively) with another basic taste receptor - the receptor for bitterness (which can mean poison both in nature and in the developed world, or at least something we have no use for, eg an alkali). Most aromatic food (think green vegetables or spices) is bitter, and salt both attenuates that perception and balances it making the combined food still desirable for our brain. You end up with an even more palatable food since you can use an aromatic (desirable) and shut out the bitterness (not always desirable) response.Umami is a different basic taste, probably related to the presence of protein (glutamate, inosinate, guanylate... trigger it - these are amino acids or salts thereof, and an indicator of easily-digestible protein presence).  <sep>  Q: Why does salt enhance the flavor of food? A: Our brains are wired to consider food more palatable if the dedicated taste receptors (one of the six basic tastes) for salt are triggered  Q: Is salt related to umami? A: Umami is a different basic taste, probably related to the presence of protein 
[EX A]: Are there compounds similar to salt that enhance flavor?

[EX Q]: CONTEXT: Coriander leaf/cilantro looks VERY similar to flat leaf parsley. When I have both at the house I sometimes resort to smelling them to know which is which. Cilantro is very strong smelling, and you'd definitely change the flavor of the dish if you left it out.Flat leaf parsley is significantly more subtle and has a much milder flavor and scent. It is not flavorless, and in a recipe that calls for a lot of it, you'd really be missing something by leaving it out.When you've got a recipe that calls for both parsley and cilantro, you're definitely going to be more able to taste/smell the cilantro more than parsley, but they'll both contribute different notes. If you have to leave one out, leave out the parsley, but don't try to make up the volume with more cilantro, as you may wind up overpowering your dish. Just leave the parsley out and proceed as normal.Do not use curly leave parsley in anything--it is tough and virtually flavorless. It is ONLY a garnish and not worth wasting your time on.  <sep>  Q: Difference between parsley and coriander(cilantro)? A: Cilantro is very strong smelling, and you'd definitely change the flavor of the dish if you left it out  Q: Are there any other differences? A: Flat leaf parsley is significantly more subtle and has a much milder flavor and scent 
[EX A]: Do they look different as well?

[EX Q]: CONTEXT: In most wheat-based recipes, gluten strands are formed while you work the dough. If you don't rest the dough, rolling can be more difficult and you may get a tougher texture in the final product.Additionally, refrigerating the dough up to a certain point will firm up the fats in the recipe (butter, etc), which will make the dough less mushy and will making rolling out the dough evenly a bit easier. Unless the dough is so firm it becomes brittle, refrigeration will make the dough less fragile in most cases.Perhaps less important, the moisture levels may become a bit more consistent throughout the dough as well.  <sep>  Q: Why should I rest gingerbread dough? A: In most wheat-based recipes, gluten strands are formed while you work the dough. If you don't rest the dough, rolling can be more difficult and you may get a tougher texture in the final product 
[EX A]:
How long should I let it rest?
