Beetroot, Carrot and Orange Soup

I have blogged the Beetroot and Carrot soup already, and declared my love for it, but it was taken to new heights by the addition of the zest and juice of an orange.  Gosh, it was so wonderful, I could have eaten the entire pot!  Anyway, if you like these flavours, they all go together really well - it is simple to make: sweat a chopped onion, some chopped carrots and peeled fresh beetroot (a ration of 2:1 carrot/beetroot) in a tablespoon or so of olive oil until softening.  Grate in the zest of a large orange, followed by its juice.  Just cover with veg stock (Marilgold is fine) and simmer gently until the veg is tender.  Puree with a hand-blender and serve.  You can add cream if you like, but we didn't, enjoying the pure, fresh tastes of the veggies and orange.
