On a recent flight in F I was sat in 1K and had a grandstand view of the galley as they prepared the food. My curry came in a large foil box containing smaller foil boxes. The lady in the galley had to warm each of the smaller boxes in a particular order and then poor them out on the plate in a certain pattern to create the "Posh just cooked by Gordon Ramsay" look.

I was quite surprised what a rigmorole this was and on a 777 with 17 F seats it took a long time for the meals to get served.

In J they get cooked in those china bowls.
