I absolutely adore this book, it's totally changed the way I eat. Who knew shallots were so awesome?! One word of advice: double every recipe. The portion sizes are bizarrely small and when using the original measurements I never had enough sauce, especially for more than one person. Otherwise, this book is flawless. It's especially helpful that each recipe tells you which foods the sauce goes with.
Some of my favorites include the Red chile brown butter sauce (great with potatoes), Roasted red pepper cream sauce, Tomato cream sauce (my absolute favorite), Arrabbiata, Sundried Tomato Gorgonzola sauce (though I now forgo the blue cheese because I'm not a fan), Lemongrass ginger cream pan sauce, and the Garlic confit aioli (making your own homemade mayo can be a bitch- but it's totally worth it).
I've had less than stellar experiences with the stir-fry sauces, such as the sweet chili garlic stir-fry (which sounds amazing but is lacking in flavor and texture) and the Thai basil nam pla (which was bland bland bland). And even though I doubled the shrimp in the shrimp butter recipe I could not taste it at all.
I recommend this book to everyone I know :)
