Brown butter pumpkin soup: a simple vegetarian autumn recipe

Chef Jackson Boxer shares a vegetarian roast pumpkin soup built on caramelised brown butter, which he calls simple in method but complex in flavour. The pumpkin is roasted with butter, and he advises cooking the butter until its water evaporates so the milk solids and sugars can caramelise. Garnishes can be as adventurous as you like.
