Vincisgrassi and Saint-Aubin

I love a collaborative cooking project so when I stayed with my friend food writer Fiona Sims at the weekend we embarked on a vincisgrassi, an elaborate mushroom lasagne from Rachel Roddy’s fantastic book, an A-Z of Pasta. It was made famous by Franco Taruschio of the Walnut Tree but you can find Rachel’s version here. (Note the fabulous crisp edges!)
