Micky's Cheese & Broccoli Soup

I have not made this yet, but if it is as nice as Mike's Broccoli and Stilton Soup - I must give it ago:

1kg broccoli
50g butter
1 onion, finely chopped
1 large potato, peeled and quartered
1,5 liters vegetable stock
120ml cream
1tbsp lemon juice
a few drops of Tabasco sauce, to taste
125g cheese salt and pepper, to taste

Remove the stalks from the broccoli and cut them into 2cm pieces. Break the florets into very small pieces and set them aside. Melt the butter in a large saucepan. Add the onion and broccoli stalks and cook covered for 5 minutes over a moderate heat, stirring frequently. Add the broccoli florets, potato and vegetable stock, bring to the boil, cover and boil for 5 minutes. Season with salt and pepper and continue cooking for +- 20 minutes or until the broccoli is soft. Using a blender or food processor, puree the mixture until smooth. Pour into a clean saucepan. Add the cream, lemon juice, and Tabasco sauce and simmer for 3 – 5 minutes. Just before serving, stir in the cream cheese until it is well mixed. Serve hot with fresh bread.
