If you haven’t checked out local Cheflebrity John Ash’s new cookbook, Culinary Birds (Running Press, $30), here’s your chance to kill a few, uh, birds with one stone. Ash will appear at Santa Rosa’s Savory Spice Shop (317 D St., (707) 284-1310) on Dec. 6 from 5-7p.m. to sign his new book (available in the store). While you’re there, grab some holiday seasonings (how old is that rosemary and nutmeg in your cupboard, honestly?) as well as tested-tips from Ash on how to serve up the best bird ever.
