Swede is very difficult to get hold of here in Germany. So if I ever see it I get some to go with the Sunday roast, as it's my favourite vegetable.
For any roast dinner including Christmas lunch I reckon to put out as many vegetables as there are people at the table. I decide which ones these are to be when I go shopping on the days leading up to Christmas.
Mostly they are just boiled and tossed in a little butter (fortunately don't have any vegans to cater for, but if I did I'd use olive oil). As I only have four burners on the hob, some will have to be done in the microwave.
But to keep it colourful, Swede, carrots and sweet corn are a very welcome addition.
