instruction:
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: The proteins in a fresh egg are too viscous, even when thoroughly beaten, to wash a baked good.The water thins the proteins so you get a nice glaze instead of a layer of scrambled egg.Older eggs have sometimes degraded enough that they don't need the water but it is easier to always add water than to make a subjective judgement on the state of your egg proteins.  <sep>  Q: What's the purpose of adding water to an egg wash? A: The water thins the proteins so you get a nice glaze instead of a layer of scrambled egg 
answer:
Many recipes I've seen call for beating a tablespoon###or so of water in with the egg for an egg wash.###What is the effect of adding the water to the egg wash when baking?


question:
CONTEXT: Without seeing the recipe and procedure, it is hard to say if the seeds are necessary, there are many recipes for Seville orange marmalade that don't call for the seeds, and some that do. There is a good chance that they aren't essential to the recipe, that being said:There is pectin in the seeds of citrus, but there is no need to grind or chop them for it to be released. Tying them in a cheesecloth bag, that would be easy to remove after cooking, would be fine. (If the recipe uses added pectin, then the seeds shouldn't be needed at all.)  <sep>  Q: Are the citrus seeds necessary when making marmalade? A: Without seeing the recipe and procedure, it is hard to say if the seeds are necessary  Q: Are the seeds necessary when making marmalade to extract pectin? A: Seville orange marmalade that don't call for the seeds, and some that do. There is a good chance that they aren't essential to the recipe 
answer:
This recipe is with Seville oranges and low in sugar, what is the best way to keep the seeds separate?


question:
CONTEXT: Iron is simply an element, so it cannot be destroyed by cooking (or generally temperature changes), as vitamins and other organic structures potentially can.Cooked spinach inevitably has a much lower water content, thus the relative density of all other components must increase. So gram for gram, it makes sense that cooked spinach should have a higher concentration of iron (and possibly some other things) than raw. However, the actual process of cooking does nothing to change the amount of iron.  <sep>  Q: Why would cooked spinach contain more iron than raw? A: Cooked spinach inevitably has a much lower water content, thus the relative density of all other components must increase 
answer:

Which is better to eat it raw or cooked ?
