There are a few errors in the book I’d like to correct here; no excuses, but I hope these post-publication edits will help if you’ve had any issues with a recipe (also: sorry!):
For the Hazelnut Cake 1/2 cup hazelnut paste should be 130g, not 225g; 1 3/4 cups hazelnut paste should be 345g, not 370g; and 2 cups roasted and skinned hazelnuts should be 340g, not 225g.
For the Pear-Chocolate Cake: 3/4 cup sugar should be 155g not 85g.
For the Chocolate Brownies: 1/2 cup butter should be 115g not 155g.
For the Chocolate Chocolate Chip Cookies: 2 1/2 cups powdered sugar should be 312g not 150g.
