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:`.

Q: CONTEXT: Not using standard practice might violate safety standards in a professional context.Technically, the important factor is whether the residues are made of something perfectly water soluble (sugar, salt, fat-free watery or alcoholic solutions, insoluble but not sticky solid particles...) or of something that is not water soluble and that will adhere to the dishes (about anything containing oils/fats). If you couldn't properly get it off your hands without soap, you won't get it off the dishes without soap.  <sep>  Q: Can some dishes be washed with only water? A: If you couldn't properly get it off your hands without soap, you won't get it off the dishes without soap 

A: Would washing dishes with soap be more efficient?###

Q: CONTEXT: I don't think so. In the mayonnaise case, all that has happened is the fat has come out of emulsion and gathered together again, so you can re-emulsify it. In the whipped cream case, you've started to create large fat crystals (butter). I guess technically it might work to heat it up to melt the butter, re-emulsify it into cream and then beat it again, but I don't think it would be worth the effort. You could go ahead and finish churning it into butter and buttermilk if you want to avoid wasting the cream.  <sep>  Q: Can ruined whipped cream be rescued? A: but I don't think it would be worth the effort  Q: Whatâs the process? A: heat it up to melt the butter, re-emulsify it into cream and then beat it again 

A: Can it be Re emulsified?###Or am I better off starting a fresh batch?

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: 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  Q: Generally in the USA, can refrigerated eggs be used past their expiration date A: you can use eggs well past their "sell by" date. A week past shouldn't have a noticeable difference 

A:
How can you tell if they are bad?
