I said a swede was a species of turnip before, and someone pointed out it wasn't. They just look similar which is why they were first called the Swedish turnip when they were imported here.
Swede is delicious, did you just boil it? It's one of my favourite vegetables.
The argument about swedes and turnips depends whether you are in England or Scotland. The yellow-fleshed thing's a turnip in Scotland (o not it's not) whereas a turnip, as any fule knows, is white-fleshed.
