Hungarian Beef Borscht Leftovers

J made borscht last weekend. It was the first time either of us had had such a dish. It was pretty tasty, but the recipe stated that you should make it 24 hours in advance and then reheat it. I had some leftover borscht for lunch the following day and it definitely was more flavorful. It seems that just about all meals are more enjoyable the second time around which boasts the question, why? Is it that the work of creating the dish has retreated farther into our memories so we can relax and enjoy the dish more? Is it that we already know what to expect from the dish and that allows us to be most pleasantly surprised if the dish seems more delicious? Does the refrigerator have some magical power? Is there some augmentive force in my Ziploc containers?

Should we make all meals one day in advance?
