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:'.

Question: 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  <sep> FOLLOWUP_Q: how can you tell if they are bad?

Answer: You will notice in older eggs that there's a growing pocket of air inside the egg when you break them


Question: CONTEXT: Sous vide cooking is a function of temperature and the surface area to volume ratio of the food in question.If you have a high surface area to volume the cooking time will be shorter. Steaks would have a higher ratio than the roast so they would take less time than the roast. The amount of the time difference is difficult to predict exactly over such a long time scale, but a rough calculation of the ratio I spoke of would be a good starting point for a compensation factor.If you have the time and your water bath can accommodate, I'd suggest keeping the roast whole and finishing in a skillet. It's much more impressive than a steak.  <sep>  Q: Should I Sous vide chuck roast or chuck steaks? A: Steaks would have a higher ratio than the roast so they would take less time than the roast  <sep> FOLLOWUP_Q: Which would taste better?

Answer: If you have the time and your water bath can accommodate, I'd suggest keeping the roast whole and finishing in a skillet. It's much more impressive than a steak


Question: CONTEXT: To clarify: forced-air (a/k/a "convection", a/k/a "fan bake") ovens rely on a fan to circulate the air in the oven. The fast-moving air substantially enhances the rate at which heat is transferred to the food. It is particularly good where you want the surface to brown, such as roasts and breads; it is not as good for more delicate items, such as custards and cakes, which can set too quickly or get dried out. For cookies, it depends on what effect you want, but many standard types do well in forced-air ovens because the fan helps ensure that the whole oven stays at a uniform temperature despite the presence of several trays. (Of course, the tray closest to the heating element will still cook faster than the one farthest away, so you will still have to swap them partway through.)The general rule for using the fan is to set the oven temperature 25 degrees F (15 C) lower than what the recipe calls for using in a regular oven. Even then, don't go strictly by cooking time, as ovens vary; rather, be sure to check on your food regularly to see how fast it is cooking. You may need to cover your food to prevent over-browning, or perhaps adjust the oven temperature.  <sep>  Q: When should I use the convection bake instead of the regular bake? A: To clarify: forced-air (a/k/a "convection", a/k/a "fan bake") ovens rely on a fan to circulate the air in the oven. The fast-moving air substantially enhances the rate at which heat is  Q: Should I use it for everything, then? A: It is particularly good where you want the surface to brown, such as roasts and breads  <sep> FOLLOWUP_Q: That is helpful to know! Is it good for roasting vegetables?

Answer:
e sure to check on your food regularly to see how fast it is cooking. You may need to cover your food to prevent over-browning, or perhaps adjust the oven temperature
