carrot and orange soup

Yum yum yum, you get the instant orange kick and the flavour just intensifies as you continue to eat! I must point out the importance of reading a recipe properly. I accidentally read '2 cups' of stock as opposed to 2 pints/5 cups, so it was thicker than it should have been, but still tasted heavenly.

What you need:
- 25g/ 2tbsp butter
- 2 leeks thinly sliced
- 450g/1lbs carrot sliced
- 2 pints/5 cups veggie stock
- zest and juice of two oranges
- 1/2 tsp nutmeg
- 150 ml/2/3 cup of plain greek yogurt
- salt and pepper
