My current favourite book is still
Soup for all Seasons . Today I put it to good use by making FOUR different soups: Creamy Baked Garlic & Onion; Carrot & Ginger; Roasted Parsnip, Lemon & Vanilla and Apple, Vine Tomato & Smoked Bacon.
Of course, I only ever cook stuff that I like, so I am not sure how much of this Number Guy will actually be allowed to eat. Hmm. Looks like dinner/tea solution may need a rethink.
