Even though it’s May now, on some days it still doesn’t feel like Spring will ever arrive. On occasional days the temperature rises above freezing, and everyone suddenly gets very excited (with whisperings of “10 degrees!”) only for it to plummet back down to -1 the next day.

This dish is somewhere between a sweet potato gratin and a lasagne- layers of rich pork mixture and sweet potato, topped off with fluffy béchamel sauce.
