Given a paragraph about cooking, and a set of conversational question answers about the paragraph, answer a follow-up question from the paragraph. The paragraph has a prefix 'CONTEXT:'. Each conversation question has a prefix 'Q:' followed by answer prefix 'A:'. The final followup question has a prefix 'FOLLOWUP_Q:'.

[Q]: CONTEXT: There are good quality vegan margarines (Earth balance, Alsan) on the market nowadays, often they are of the interesterified instead of the hydrogenated variety. They are designed to behave and taste similar to butter instead of (as many cheap margarines seem to do) staying spreadable at temperatures where butter would be very firm. Unlike pure coconut or palm oil, they do not act very brittle when cold, and also they soften gradually instead of suddenly melting like eutectic solder. These should be on the top of the list of things to try...Also, some recipes recommend using more than one type of fat in pastry, for more interesting texture (eg such margarine, and smaller flakes of a hardened coconut fat).  <sep>  Q: Are there any butter alternatives for baking pastry? A: There are good quality vegan margarines (Earth balance, Alsan) on the market nowadays, often they are of the interesterified instead of the hydrogenated variety  <sep> FOLLOWUP_Q: Would that give the dough the same consistency as when I use butter?
[A]: They are designed to behave and taste similar to butter instead of (as many cheap margarines seem to do) staying spreadable at temperatures where butter would be very firm


[Q]: CONTEXT: Yes, you can use eggs well past their "sell by" date. A week past shouldn't have a noticeable difference.The older the eggs get, the more evaporation that will take place (because the eggs are washed, so they don't have a protective layer).You will notice in older eggs that there's a growing pocket of air inside the egg when you break them. (for me it tends to be on the more rounded end, but I don't know if it has to do with how you orient the eggs in storage).I know that I've used eggs more than a month past the "sell by" date, and I wouldn't be surprised if I've gone two months. It's only really a problem in baking, as the egg whites won't contribute the same amount of moisture as if they were fresh. And maybe for hard boiled eggs if you want them pretty, as you'll end up with a void where the air pocket is.  <sep>  Q: How long can refrigerated eggs last past their date? A: A week past shouldn't have a noticeable difference  Q: I have some eggs that expired last week, so will they still be OK to cook with? A: It's only really a problem in baking, as the egg whites won't contribute the same amount of moisture as if they were fresh  <sep> FOLLOWUP_Q: Do they last past their expiration date if they are refrigerated?
[A]: you can use eggs well past their "sell by" date. A week past shouldn't have a noticeable difference


[Q]: CONTEXT: As baka has said, more volatile components of the wine will be released with more wine surface exposed.Also, this not only releases aroma but also helps the wine to "breathe" and oxidize, which is why you open the red wine bottle half an hour before serving it (so that this process starts), and why you might pour the wine into a decanter.This process accentuates the flavors and aromas of the wine. It is not very much necessary with younger, colder served wines (e.g. vinho verde).In young, sparkling wine, a larger glass will disperse the bubbles faster, as well as warming it. This is undesireable, hence the smaller, narrower glasses.Aged white wine should behave similarly to aged red wine, although it doesn't need to breathe as much.  <sep>  Q: Why are red wine glasses wider than white wine glasses? A: a larger glass will disperse the bubbles faster, as well as warming it  <sep> FOLLOWUP_Q: Will the wine taste different if I don't use the correct glass?
[A]:
