Turn on the reading lamp. Once again, Barbara Bush’s book show is coming to town. We had a great time last year grabbing some cookbooks and read them on the grass in front of the Capital (in the best weather you can hope for this time of year). On Saturday this year, Paula Disbrowe and Robb Walsh are ‘cooking off’ with cast iron at noon. On Sunday at 2:00, our first lady of cheese, Paula Lambert will be speaking about her perfect mozzarella.
