The Art and Soul of Baking, which I've mentioned a bunch of times this year. This book, has without fail, the best recipes and instructions in it. I've never had a recipe go awry. Everything has been delicious and come out beautifully. My husband has great taste in cookbooks!
I love that this is a savory muffin. I bought a basil plant for my kitchen window and this is the first recipe I've used it for. The smell of freshly cut basil is intoxicating and wonderful.
