Couldn't possibly read it cover to cover, so the test surely had to be to cook a couple of things from it. First, Delia's "Cornish Pasty Pie":
Click the image if you want to see it bigger. It was... actually... really scrummy. And not to hard to make. Wife had a double portion (!)
Then, to see if I could really stretch myself with Delia's help, "Choux pastry chocolate and hazelnut buns":
Not so successful, certainly didn't form a single mass in the saucepan "coming clearly away from the sides". Maybe because I used Stork instead of butter. Took HOURS to make, and probably constitutes about a month's worth of Weightwatchers Points. See the size of the work surface I have to use? That's three side plates you're looking at. It would be interesting to see Delia cook in a real world kitchen.
