Apart from the fact that Julie Powell is a whole lot more foul-mouthed, albeit also funnier, in her writing than Amy Adams portrays her in the movie, what strikes me about the book is the sheer pleasure Julie gets from her cooking. She cooks not from a vague sense of "shoulds", from a desire to follow the latest tenet in the religion of "thou shalt/shalt not eat this-n-that", but because it's sheer, unadulterated pleasure. Well, the eating is, anyway; the cooking, not always so much (the story of her first extraction of marrow from a beef bone is rather entertaining. Even if she didn't find it so at the moment).
Here, listen to this:
"Julia taught me what it takes to find your way in the world. It's not what I thought it was. ... It's joy. [...] I didn't understand for a long time, but what attracted me to MtAoFC [Mastering the Art of French Cooking, Julia Child's book] was the deeply buried aroma of hope and discovery of fulfillment in it. I thought I was using the book to learn to cook French food, but really I was learning to sniff out the secret doors of possibility." (page 356 in the paperback edition).She's talking about a cookbook here, people.
In fact, that last quote reminds me of nothing so much as my favourite un-diet book, French Women Don't Get Fat (Mireille Guiliano). It's all about that: eat delicious food, in portions small enough so you can enjoy it, because it's just so dang good. Because it's all about life. Not about calories, not about "thou shalt". The joy of eating, eating for joy.
Life, the universe, and a grilled steak with greek salad, pita bread and hummus. Oh yeah.
