Question: CONTEXT: Mast O Khiar, as you mention mainly consist of plain yogurt and cucumbers and most recipe do not require much more than that. Because of such, the shelf life for the yogurt product will be the shelf life of the yogurt itself. If it is a store bought yogurt, then the shelf life should be about 2 weeks in the refrigerator.Make sure to store the sauce in an air-tight container. Most tubberware should work. Those soup containers from Chinese takeout orders work perfectly.EDIT: After a bit of a debate in cooking chat, I decided to change my answer a little. The reason I said 2 week is because personally I had eaten 2 week old Mast O Khiar. However it could be recipe dependant so it could be different for a different recipe. However it is very easy to tell whether yogurt OR cucumber is bad.Mast O Khiar should have a very fresh/clean aroma. When yogurt turn bad, it releases a rancid smell. If it smells bad, dont eat it.If you see fuzzy mold it's a good idea to throw it out.  <sep>  Q: I made kubideh kabobs with saffron rice for my fiance and I last night, and it was a huge success. However, my fiance wished we had some mast o khiar (yogurt-cucumber sauce) to go with it, as what we would normally get from a kabob takeout place### Now, given that this is the first time Persian food has ever been made in this house, I have concerns about any reasonably sized batch of this yogurt sauce being consumed in time. A: Mast O Khiar, as you mention mainly consist of plain yogurt and cucumbers and most recipe do not require much more than that  <sep> FOLLOWUP_Q: how long might this be safely stored in a refrigerator?

Answer: Yes


Question: CONTEXT: If a lid doesn't have a vent and the pot does not have any sort of locking mechanism like a pressure cooker, then the pressure of the steam inside will lift the lid off the pot and steam will escape. That was the "dancing" of the lid that you experienced. Venting holes in a lid just let some steam escape so the lid doesn't bang around, having a vent hole or not wouldn't make your idli's sticky.  <sep>  Q: Must a lid for a pot used for steaming be vented? A: If a lid doesn't have a vent and the pot does not have any sort of locking mechanism like a pressure cooker, then the pressure of the steam inside will lift the lid off the pot and steam will escape  Q: I have a lid that fits the Instant Pot exactly, but it lacks the steam release vent. How much does this matter? A: Venting holes in a lid just let some steam escape so the lid doesn't bang around  <sep> FOLLOWUP_Q: For steaming, would the absence of a vent cause too much steam to remain in the pot?

Answer: No


Question: CONTEXT: Can't comment on the nutritional side of things, but the main reason I can think of for not always including it is that it has a slightly different flavour. A much more intense lemon flavour is provided by the zest while the juice has the more tart elements (and of course water).If you're just interested in avoiding waste, you can freeze the zest.  <sep>  Q: Are there any reasons not to include the zest when citrus juice is an ingredient? A: the main reason I can think of for not always including it is that it has a slightly different flavour  Q: How does the zest change the flavor? A: A much more intense lemon flavour is provided by the zest  <sep> FOLLOWUP_Q: Is it the same for all citrus fruits?

Answer:
Yes
