I've not been to this New York bakery, but had to have the book! I've been looking forward to it for ages. Lovely little baking book, a good addition to any bakers collection. As you would expect, U.S. measurements, so (for non American bakers, like me) a set of American measuring cups are necessary and you also need to know that 1 tablespoon butter = 1/2 oz (half an ounce) of butter. With the cups and this information though, you should be fine.
Some great bars, blondies and brownies including Fat Witch brownies, white chocolate bars, raspberry bars, rum and raisin bars, cranberry blondies, Congo bars, orange walnut blondies, hermit bars and the one I'll bake first turtle witches - brownies with caramel and pecans , how yummy does that sound?! Can't wait to get baking.
