Remember that the pursuit of happiness, in the Declaration, is not a quest or a pastime, but an unalienable right.. Everyone has the right to actually be happy, not just try to be happy. To use a metaphor: You don't just get the chance to make the baseball team, you are guaranteed a spot.
How long does an unopened package of mayonnaise last at room temperature? Properly stored, an unopened package of mayonnaise will generally stay at best quality for about 3 to 4 months after the date on the package.
Foods containing homemade mayonnaise should be kept refrigerated, and should be eaten on the same day. The two-hour rule applies here too, and any food that's been left out for two hours should be discarded. To make mayonnaise safely at home, buy pasteurized eggs from the refrigerator section of your supermarket.
