Creamy Cauliflower Soup with Stilton

Velvety cauliflower soup, with melted Stilton. I find cauliflower to be such an undervalued vegetable, you really should start eating it more often; it is especially worthwhile in soup. It also easily purées.

Serve topped with garlic crostini, on which a little Stilton combined with crème fraîche is melted.
