Maggie Beer's Borscht

I have never made this before, but beets are in so I thought I'd give it a crack. Apparently this one isn't authentic, but its Maggie's so I trust it. Its pretty good - so good in fact we ate it for breakfast cold.
Method
Heat the butter and oil in a large pot and let sweat for a few minutes, add in the beets and celery and stir with the salt and pepper. Cover with the stock and let simmer on low for 2 hours.
Let cool for another hour or overnight and then push through a blender. Serve cold with dill and yoghurt any time of day.
