Danielle Alvarez's menus are about celebrating restraint and seasonality. Her menu at Fred’s in Sydney (think of it as a trip to Berkeley via Paddington) is pure San Francisco,thanks to the many years she spent honing her skills at Alice Waters'Chez Panisse. This three-course Easter menu will serve a big group,starting with this salad. Persimmons come into season at this time of year and add a beautiful sweetness. If you can't get a hold of persimmons,pears work well.
