Is it a condition for expiation of an oath to feed one and a half kilograms, or is a satisfying meal sufficient?

The expiation for an oath is to feed ten poor people from the average of what you feed your own family, or to clothe them, or to free a believing slave. These three options are given as choices. If you are unable to do any of them, then you must fast for three days. The amount of food for each poor person is one mudd of the common staple food of the country, which is estimated at 750 grams. Some say half a sa' (1.5 kilograms), which is more cautious. The food can be given raw or cooked. If cooked, the poor person must be fed two meals (lunch and dinner) and not just one meal. This is the view of the majority of scholars.
