If there is one constant here in Castellet, Provence it is the sheer beauty (and quantity) of the food we are treated to: foie gras, roast lamb, crisp green salad and peaches drenched with red wine at Marc and Marcia’s; bowls of delicately-flavoured sardine, aubergine, tuna and goat’s cheese dips with toasted baguette at Café de France in Lacoste village; and the stunning dinner dear Caro Nigella’ed up in her kitchen tonight (more on that in a moment).
