Since you and jo have both mentioned Paul Hollywood, I looked him up. WOW!!!! I guess I better start watching that show. lolIn the H books I have:
Donna Hay (Australian chef - signed copy I found in a charity shop)
Ambrose Heath - vintage books from and English cookery writer
Nicola Humbert - technically a book about the history of recipe books but it contains recipes too
and like jojopops70, a Paul Hollywood book
I have one planned from Donna Hay and possibly a second from Ambrose Heath.
