Red Prawn and Mango Curry: This is one of the easiest suppers to make, but somehow, however much I know this, it always surprises me. Not in the cooking, so much as in the eating: I can't believe, each time anew, how deep and textured and full-throttle, in a sweet, comforting way, this tastes, when all I've done is a bit of shopping and some light stirring.
