A blog by a public-relations firm seems a high-risk venture, with its potential to both offend existing clients and scare off possible clients, so it will be fun to see how Sacramento's newest food blog develops. How candid will its contributors be? How self serving? At the outset, Sac FHoodies is personal and gentle, amounting to an interview with Kira O'Donnell, owner of The Real Pie Company at 12th and F, a few recipes, and brief profiles of the blog's 10 contributors, all with the Sacramento office of the public-relations firm Fleishman-Hillard. It's light, but as we say, it's just getting started.
