Saturday, 7pm, LifeStyle Food Word has it that Charles Saatchi, 70, is dating style guru Trinny Woodall ( What Not to Wear) just two months after he and Nigella Lawson, 52, divorced. Their marriage proved to be a recipe for disaster after he was caught on camera apparently throttling Nigella in a restaurant. Nigella, bless her, has kept a dignified silence — as one would expect of the daughter of Nigel Lawson, a former chancellor of the Exchequer and now Lord Lawson of Blaby. There are hints she’s being comforted by another celebrity chef, Anthony Bourdain ( Parts Unknown, No Reservations), but tonight she’s where we love her: in the kitchen licking her fingers. Asian chicken teriyaki with noodles and sugar snap peas and Venetian carrot cake with rum mascarpone cream are on the menu.
