Attention Goop groupies: Gwyneth Paltrow, "someone who gets in bed and reads cookbooks cover to cover as if they were novels," has decided to introduce a potluck-style cookbook club. First up is the Roberta’s Cookbook: Paltrow cooked six recipes (no pizza, but she did make fried chicken) and hosted the world's most perfect alfresco dinner party, of course. Now she wants you to do the same! All you have to do is whip up homemade pizza dough and use the hashtag #goopcookbookclub. Easy.
