New Year, New Broccoli Soup

I was delighted to get Leith's Vegetarian Bible for Christmas.
The first thing I made from it was the first recipe in there, broccoli soup.
I've used a few different recipes for this in the past (Gordon Ramsay and Anthony Worrall-Thompson spring to mind), and they've been disappointing. Thankfully, this one is brilliant, and straightforward.

Ingredients: 1 0z butter, 1 large onion (sliced), 1 lb broccoli, 1 pint veg stock, salt & freshly-ground black pepper, 1/4 pint milk, 1/4 pint single cream, & freshly-grated nutmeg.
Serves 4.

Method: Large saucepan- melt the butter- when foaming, add the onion and fry on a low heat until soft & transparent.
Chop the broccoli florets & stalks, and just discard the very tough bits. Add to the pan (with the stock). Season with salt & pepper, and simmer for 30 minutes.
Puree the soup in a food-processor or blender, & return to the pan. Stir in the milk & cream, and add as much nutmeg as you like- reheat without boiling.

And there you go- the nicest broccoli soup I've ever had, especially with some crumbled Stilton mixed in.
