5 The eiruv must remain in tact until you have prepared all your Shabbos needs. If the bread (of the eiruv) was lost or eaten, it also does not matter; and you are allowed even to bake for Shabbos. But if the cooked food was lost or eaten, if a kazayis is left it doesn't matter. But if less than a kazayis is left, it is forbidden to cook [for Shabbos,] just as if you had made no eiruv. What should you do if you made no eiruv? If you thought of it after the morning (Yom Tov) meal, and in that community there is no other Jew who made an eiruv, you are perrmitted to cook only one pot, bake only one loaf of bread, and light one candle for Shabbos. If you thought of it before cooking the morning (Yom Tov) meal, you may cook all kinds of foods in a large pot and leave some over for Shabbos. If there is someone there who made an eiruv, you should give him as a gift, your flour, meat and all other ingredients. The one who made the eiruv acquires possession of these items by lifting them up, and then he may cook and bake for you, even in your house though you did not make an eiruv.
