Regarding the chopped liver recipe in Weekend (My life in food, 13 September): yes chopped liver is very much a staple in most Jewish households, but I very much doubt whether anyone would sauté the onions in butter as it is totally against Jewish dietary laws to mix milk (or milk products) and meat. In fact, it is a requirement to leave three hours after a meat meal before consuming milk, hence black tea or coffee and no custard or cream with dessert.
