For my grandchildren Paul, David, Uaan, and Ty. This is a book for their future. And for Burwell, for putting up.

In memory of Hendrik Houbein (1796–1874), grower of cabbages, carrots, onions, and potatoes in North-West Frisia, and Uncle Wim Schild, who taught me about vegetables, fruits, and chickens in his magic food garden at Laren, North Holland.
