So I had this massive barbecue last weekend that featured many things that required lime juice (guacamole, salsa, flank steak marinade, mixed drinkss, etc.). At the start of my prep, I just went ahead and juiced like a case of limes for all of the aforementioned uses. Of course, I now have about a quart of lime juice sitting in my fridge. I am at 6 days from the barbecue. My question is, how long does lemon or lime juice last once you've separated it from the lemon or lime? What is the shelf life? Does it actually spoil?
