Mansion Range
This was a range for a super-large house with a full compliment of servants, including a cook called Cook. This was for the sort of house you see in Newport, Rhode Island - for the really rich rich.
In a household like that, you needed near-commercial capability. A typical day's work for it would include breakfast for family and guests, a lunch for Milady and her friends (where they might discuss the merits of Jungle Red nail polish and the like), a five o'clock tea with pastries and sandwiches, and then a seated dinner. In the good old days of money that had manners, a formal dinner in what Emily Post termed a "great house" was usually for 24 people.
In addition, staff and children had to be fed. Staff always ate separately from family, children did on formal occasions until they were teenagers who had proved they had the deportment expected at an adult function.
It made for a busy kitchen.
