[EX Q]: Question: How many books has the author David used recipes from written? Passage:Granger realises that she will need to ask for small portions at the first meal to preserve her appetite, despite asking she is presented with turkey slices and sixteen types of vegetables. She finishes this and is presented with a whole Christmas pudding to eat which she initially thinks is for the three to share. Now starting to feel full up she goes to the second where David is using recipes from a Delia Smith book. He presents her with a large plate of pasta, then a whole fish and finally the turkey. After initially declining David's offer of more Brussels sprouts she reluctantly accepts as it's a competition between him and Hugo as to who eats more sprouts, David or the guest (representing Hugo), she gives Hugo his first win against his father in any competition. Now completely full up she crawls to Alice's house and in vain tries to get Alice and her family to offer her just a cup of tea by telling a fictionalised version of the events she's been through. Mrs Tinker serves her balls of stuffing as a starter and then a main course. After the third meal the vicar gets a cab home (which is just opposite Alice's). Newitt then arrives offering her the fourth lunch and she reluctantly goes with him where he serves a large selection of food including tripe, all of which is offered to her as Newitt has a stomach upset. The vicar is finally given a lift home in the bucket of his tractor.
